Web= K (K), so by inclusion-exclusion (L) = X K L ( 1)l(L) l(K) n K ; where l(L) is the number of parts of L. We can count all sorts of sets of permutations defined by descent sets by added up (L) for appropriate L. We get exponential generating functions since n L is the coefficient of xn=n! in xL L!:= xL1 L1! xLk Lk!: WebMar 4, 2024 · Permutations with repetition by treating the elements as an ordered set, and writing a function from a zero-based index to the nth permutation. Wrapping this function in a generator allows us terminate a repeated generation on some condition, or explore a sub-set without needing to generate the whole set:
