Provides routines for combinatorial enumeration including generation of all combinations, permutations, and lattice points on hypercuboids and simplex lattices. Includes utilities for multinomial distributions: the multinomial probability mass function, random sampling with varying parameters, and encoding conversions between simplex representations. Also supplies exact and log-scale factorial computation and the generalized binomial coefficient for real-valued n. Package functions include procedures described in Reingold, Nievergelt and Deo (1977) Combinatorial Algorithms: Theory and Practice (dl.acm.org/citation.cfm?id=1096489), Feller volume 1, and Nijenhuis and Wilf (1978) Combinatorial Algorithms for Computers and Calculators (ISBN 0125192606 / 9780125192606).
