Work out superfactorial instantly with clear inputs, formula shown and shareable results.
Sloane and Plouffe's superfactorial multiplies together all the factorials up to n: sf(n) = 1! × 2! × … × n!. It grows far faster than the factorial itself.
Superfactorial
sf(n) = Πₖ₌₁ⁿ k! = 1! × 2! × … × n!
1 × 2 × 6 × 24 × 120 = 34560.
Yes. Pickover's superfactorial is a tower of factorials and grows unimaginably faster; this calculator uses the product definition.
