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.
A complete factorial experiment involves no aliasing of effects. On the other hand, it can be expensive if experimental condition overhead costs are high. A fractional factorial experiment is usually less costly than a complete factorial. On the other hand, it will always involve aliasing of effects.
