A lower bound on the number of elements outside a closed subset of aC-basis of a commutativeC-algebra with dual a table algebra is derived, as is an equivalent condition for when the lower bound is met. As corollaries, lower bounds are obtained on the number of primitive idempotent matrices of rank greater than 1 in the adjacency algebra of a commutative, imprimitive association scheme; and, for a given normal subgroupNof a finite groupG, on the number of irreducible characters ofGwhose kernels do not containN, and on the number of conjugacy classes ofGnot contained inN. Also found are equivalent conditions for when these lower bounds are met.
