Table of factorials: values of n! from 1 to 41

The table of factorials is a reference material that contains the values of n! (factorial of n) for numbers from 1 to 41. Factorials are widely used in combinatorics, probability theory, and in solving problems in algebra.

The factorial of a number is defined as the product of all natural numbers from 1 to n inclusive.

For example, 6! = 1 · 2 · 3 · 4 · 5 · 6 = 720
