Py permutations
WebA given permutation has a rank among all the possible permutations of the same elements, but what that rank is depends on how the permutations are enumerated. … WebIt’s surprising how quickly the number of permutations and combinations grows as we add elements to a set. This combinatorial explosion is captured by the formulas in Table 6-2.For example, a set of 10 elements has 10!, or 3,628,800, possible permutations, but a set of twice as many elements has 20!, or 2,432,902,008,176,640,000, permutations.
