WebDerivation by inclusion–exclusion principle One may derive a non-recursive formula for the number of derangements of an n -set, as well. For 1 ≤ k ≤ n {\displaystyle 1\leq k\leq n} we define S k {\displaystyle S_{k}} to be the set of permutations of n objects that fix the k {\displaystyle k} -th object. WebAug 14, 2024 · I have implemented a generalization to the inclusion-exclusion principle, which extends the principle from sets to more general objects. In short the principle calculates the left by doing the calculation on the right In order to extend this to general objects, these objects need to have some structure (some defining property).
