Fast Growing Hierarchy Calculator !!better!! < 2026 Release >

: This level can describe numbers far beyond any named constant in physics. Calculator Logic

If the index $\alpha$ is $0$: $$f_0(n) = n + 1$$

Now wrap your mind around this: ( f_\omega+1(3) ) applies ( f_\omega ) three times, starting from 3. The first ( f_\omega(3) ) is that insane number. Then you apply ( f_\omega ) to that insane number. And then again. The result is barely within the realm of describable googology.

Successor:

def symbolic_reduction(self, alpha, n, depth=0): """ Returns a string showing how the function expands, useful for visualizing f_3 or f_w without computing massive numbers. """ indent = " " * depth prefix = f"indentf_alpha(n)"

Below is a working designed to handle the hierarchy up to $\varepsilon_0$. It utilizes JavaScript’s native BigInt to handle large integers.

# Increase recursion depth for deep hierarchical calls sys.setrecursionlimit(2000) fast growing hierarchy calculator

A "fast-growing hierarchy calculator" is a computational tool that automates this recursive process. The core tasks for such a calculator are:

In the world of —the study of large numbers—few concepts are as fundamental or as mind-bogglingly vast as the Fast-Growing Hierarchy (FGH) . It is a mathematical framework used to define functions that grow faster than nearly any standard function, such as exponentials, tetration, or even the Ackermann function.

The Fast-Growing Hierarchy (FGH) is a family of functions used in mathematics and computer science to classify the growth rates of functions. It is the gold standard for measuring the size of large numbers, from the merely huge (like $10^100$) to the incomprehensibly large (like Graham’s Number and TREE(3)). : This level can describe numbers far beyond

), it hits the limit of algorithmic computability. Beyond this point, no computer program or calculator can systematically evaluate the functions. Conclusion

An upper bound in Ramsey theory, utilizing 64 layers of Knuth's up-arrows.
