Let’s assume you have found a functional FGH calculator (e.g., a custom JavaScript tool on a googology forum or a Python library like fgh.py ). Here is how you use it. fast growing hierarchy calculator

In the realm of googology—the study of mind-bogglingly large numbers—standard scientific notation quickly breaks down. When numbers become too massive to be expressed by exponents, or even by tetration and Knuth’s up-arrow notation, mathematicians turn to the .

(for (\alpha < \mu), where (\mu) is a large countable ordinal) that grow increasingly fast as the index (\alpha) increases. A primary example is the , which covers all ordinals below the ordinal (\varepsilon_0). Safeguards: fα+1(n)=fαn(n)f sub alpha plus 1 end-sub of

You must enter the subscript (the "level"). Most calculators accept standard notation:

(for a limit ordinal (\alpha)):
