WebOct 31, 2024 · A permutation of some objects is a particular linear ordering of the objects; P ( n, k) in effect counts two things simultaneously: the number of ways to choose and order k out of n objects. A useful special case is k = n, in which we are simply counting the number of ways to order all n objects. This is n ( n − 1) ⋯ ( n − n + 1) = n!. WebFactorials. A factorial is represented by the sign (!). When we encounter n! (known. as ‘n factorial’) we say that a factorial is the product of all the whole numbers. between 1 and n, where n must always be positive. For example. 0! is a special case factorial. This is special because there are no positive numbers less than zero and we ...
