Creating a comprehensive list of large numbers beyond a trillion is a fascinating journey into the world of mathematics and numerical notation. While it may not be feasible to list every single number in a 2000-word blog post, we can explore the most commonly used and notable large numbers, along with some interesting facts and applications.

## What Comes After Trillion?

*After a trillion comes a quadrillion, which is a thousand times larger, denoted as 10^15. The sequence continues with quintillion (10^18), sextillion (10^21), septillion (10^24), octillion (10^27), nonillion (10^30), and decillion (10^33). These numbers grow exponentially, representing increasingly vast quantities in mathematical and scientific contexts.*

**Quadrillion (10^15)**:- A quadrillion is 1,000 times larger than a trillion.
- In the short scale (used in the United States), it’s 1 followed by 15 zeros.
- In the long scale (used in some European countries), it’s 1 followed by 24 zeros.

**Quintillion (10^18)**:- A quintillion is 1,000 times larger than a quadrillion.
- It’s used in various scientific and economic contexts, such as measuring global energy consumption.

**Sextillion (10^21)**:- A sextillion is 1,000 times larger than a quintillion.
- It’s used in astronomy to describe the estimated number of stars in the observable universe.

**Septillion (10^24)**:- A septillion is 1,000 times larger than a sextillion.
- This number is used in physics to describe the Avogadro constant, which represents the number of atoms or molecules in a mole.

**Octillion (10^27)**:- An octillion is 1,000 times larger than a septillion.
- It’s used in mathematics and science, especially in combinatorics and probability.

**Nonillion (10^30)**:- A nonillion is 1,000 times larger than an octillion.
- It’s occasionally used in discussions of the size of large data sets or the number of possible chess game variations.

**Decillion (10^33)**:- A decillion is 1,000 times larger than a nonillion.
- It’s used in theoretical physics and cosmology when discussing large-scale phenomena like the number of particles in the universe.

**Undecillion (10^36)**:- An undecillion is 1,000 times larger than a decillion.
- It’s applied in extremely large-scale mathematical calculations and in discussions of astronomical quantities.

**Duodecillion (10^39)**:- A duodecillion is 1,000 times larger than an undecillion.
- It’s used in mathematical discussions involving large factorials and permutations.

**Tredecillion (10^42)**:- A tredecillion is 1,000 times larger than a duodecillion.
- This number often appears in discussions of hypothetical scenarios, such as the number of possible chess positions.

**Quattuordecillion (10^45)**:- A quattuordecillion is 1,000 times larger than a tredecillion.
- It’s used in combinatorics and discussions of extremely large quantities in various fields.

**Quindecillion (10^48)**:- A quindecillion is 1,000 times larger than a quattuordecillion.
- It’s occasionally used in discussions of population growth, especially in the context of projecting future populations.

**Sexdecillion (10^51)**:- A sexdecillion is 1,000 times larger than a quindecillion.
- It’s used in theoretical mathematics and physics, especially when dealing with astronomical scales.

**Septendecillion (10^54)**:- A septendecillion is 1,000 times larger than a sexdecillion.
- It’s rarely used in practical contexts but may appear in specialized mathematical discussions.

**Octodecillion (10^57)**:- An octodecillion is 1,000 times larger than a septendecillion.
- It’s mostly a theoretical concept, relevant in extremely large number theory and calculations.

**Novemdecillion (10^60)**:- A novemdecillion is 1,000 times larger than an octodecillion.
- This number is seldom used outside of abstract mathematical discussions.

**Vigintillion (10^63)**:- A vigintillion is 1,000 times larger than a novemdecillion.
- It’s a common point at which many lists of large numbers stop due to the sheer scale of these numbers.

**Centillion (10^303)**:- A centillion is often used colloquially to refer to an extremely large, unspecified number. It’s not an officially recognized mathematical term.

It’s important to note that once we reach numbers like vigintillion and centillion, these values become so enormous that they have limited practical applications and are primarily used for theoretical discussions in mathematics and science.

Beyond these numbers, you can continue adding “illions” by increasing the exponent by three each time. However, these numbers become increasingly abstract and are rarely used in real-world contexts. Exploring larger numbers is a fascinating exercise in understanding the vastness of mathematical notation, but practical applications are limited due to the sheer magnitude of these values.

## FAQs

**What is after googolplex?** There isn’t a widely recognized standard term for a number larger than a googolplex. A googolplex is already an incredibly large number, written as 10^(10^100).

**What is this number 1000000000000000000000000000000?** This number is one followed by 27 zeros and is equal to 1 octillion in the short scale numbering system.

**What comes after the zillion?** The term “zillion” is informal and not part of any standard numbering system. It is often used to represent an extremely large, unspecified number. There is no official term that comes after it.

**What comes after 3 trillion?** After 3 trillion comes 4 trillion.

**What comes after Millinillion?** “Millinillion” is not a recognized term in standard numbering systems. It’s possible you meant “million,” which is followed by “billion,” “trillion,” and so on.

**What is bigger than a Googolplexianth?** There is no standard term for a number larger than a googolplexianth.

**Is Omega bigger than infinity?** In mathematics, both “omega” and “infinity” represent concepts related to the concept of infinity, but they are not typically compared in terms of size because they are not real numbers. Omega is often used in set theory to represent the least upper bound of an infinite set of numbers, while infinity represents the concept of being unbounded or without limit.

**Is Pi bigger than infinity?** No, pi (Ï€) is not bigger than infinity. In mathematical terms, infinity is not a real number, but rather a concept that represents an unbounded, limitless quantity. Pi is a specific irrational number (approximately equal to 3.14159) that is finite.

**What does 999,999,9999 mean?** It appears that there might be a typo in your question. “999,999,9999” seems to be a combination of numbers and an extra digit. If you meant “999,999,999,” it represents 999 million, 999 thousand, and 999.

**What comes after infinity?** In mathematics, “infinity” is not followed by a specific number because it represents an idea of unboundedness and limitless quantities. It is not a real number, and there is no “next” number after infinity.

**What’s the last number before infinity?** There is no last number before infinity because infinity is not a specific number and does not have a predecessor in the traditional sense of counting. It represents an unbounded and limitless concept.
