The combustion of the hydrogen and of the oxygen at the point of the cylinder produces solely the vapor or steam of water. Five Weeks in a Balloon by Verne, Jules View in context.
Factorial number system. In combinatorics, the factorial number system, also called factoradic, is a mixed radix numeral system adapted to numbering permutations. It is also called factorial base, although factorials do not function as base, but as place value of digits.
In mathematics, a factorial is a function applied to natural numbers greater than zero. The symbol for the factorial function is an exclamation mark after a number, like this: 2! The usual definition of ân factorialâ is ân! = n * (n â 1) * (n â 2) *â¦* 2 * 1,â where ânâ is a positive integer. The first handful of factorial values from positive integers are: 1! = 1; 2! = 2; 3! = 3*2 = 6; 4! = 4*3*2 = 24; and 5! = 5*4*3*2 = 120.
