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.
For the vast majority of factorial experiments, each factor has only two levels. For example, with two factors each taking two levels, a factorial experiment would have four treatment combinations in total, and is usually called a 2Ã2 factorial design.
