# Challenge: create a large number using an esoteric programming language [duplicate]

I enjoy large numbers and esoteric programming language, so I decided to combine them into a programming challenge. Your goal is to push the limits of esoteric languages like BF or Pyth and return the largest number possible in the shortest amount of code.

# Rules

You must use an esoteric programming language. See here for a list of banned languages.

Your code should be less than 512 bytes. Your score is based on large its output is. The latter will be based on a fast-growing hierarchy approximation.

Your code must output a large integer, at least $$\10^{10^6}\$$, and the output must be deterministic. Infinity is not allowed.

The final result should either be written to STDOUT or to a variable.

Your program must terminate in a finite amount of time with an infinite amount of memory.

No external resources are allowed, so you can't import a function unless it is built in to the programming language.

• I have seen this post, and myself entered into it. The rules were slightly looser there. I instead was looking for how you could push the limits of languages such as BF or Pyth to extremely big numbers, while keeping your code efficient. Nov 29 '21 at 17:42

• It's unclear how the scoring works. You say it's based off of both code length and output size, but there's no specification of what formula should be used. Nov 29 '21 at 18:11
• Sorry nevermind, it should just be based on just output size. Thanks for pointing it out. Nov 29 '21 at 18:12
• Largest Number Printable is still also quite similar, but it is still not limited to esoteric programming languages, and the maximum code length, along with other things, is severely shorter. Nov 29 '21 at 18:17
