# numgens(SchurRing) -- Number of generators of Schur ring.

## Description

Given a Schur ring S, the function numgens outputs the number of generators of S. This is equal to the relative dimension of S over its base ring, and also to the maximal number of parts of a partition allowed as an index for the elements of S.
