**subset_test**,
a FORTRAN90 code which
calls subset() to
enumerate, generate, randomize, rank and unrank combinatorial objects
including combinations, compositions, Gray codes, index sets, partitions,
permutations, polynomials, subsets, and Young tables. Backtracking
routines are included to solve some combinatorial problems. Some routines
for continued fractions are included.
