... − 1 k − 1  m k = m(m + 1) n−1 m-colored compositions of n (so if m = 1, we have 2 n−1 ordinary compositions). Let Comp (m) (n) denote the set of all m-colored compositions of n, and define C (m) :=  n≥0 Comp (m) (n), where ... number f (m) n (α) of m-colored permutations w with colored descent composition α. Corollary 2.3. The total number of saturated chains from ∅ to rank n is equa...
