Fast Growing Hierarchy Calculator High Quality [2021]

To compute (f_\omega+1(2)):

indexed by α, starting from small functions and progressing to unimaginably fast-growing ones. f₀(n) = n + 1 : Simple succession. f₁(n) = 2n : Multiplication. : Exponential growth. : Tower of powers (tetration). : The first transfinite step, growing faster than any for finite k. As the ordinal α increases (e.g., ), the functions grow faster than any function previously defined [1].

: Excellent for computing lower levels of the hierarchy and translating Knuth up-arrow notation or Steinhaus-Moser notations into comparable FGH ranks. To compute (f_\omega+1(2)): indexed by α, starting from

Different standards exist. The most common are:

When your engine encounters a limit ordinal, it needs a strict lookup system for fundamental sequences ( α[n]alpha open bracket n close bracket ). Here is the standard standard assignment model up to ε0epsilon sub 0 ω[n]=nomega open bracket n close bracket equals n Rule for Coefficient Terminals ( is a successor ):

As of 2025, the frontier moves toward:

Use Python (for fractions and big ints) or Rust (for performance and safety). Avoid JavaScript for large n.

The calculator should also display the exact fundamental sequence rule in effect, e.g., (\varepsilon_0[0] = 1, \varepsilon_0[n+1] = \omega^\varepsilon_0[n]).

The Fast Growing Hierarchy (FGH) is an ordinal-indexed family of rapidly increasing functions, fundamental in computability theory and proof theory. Unlike simple sequences, FGH leverages the concept of (like ω, ε₀, Γ₀) to create a framework where functions can be compared and categorized by their growth rates. : Exponential growth
