Abstract
A (k; r, s; n, q)-set K is defined to be a set of k points in PG(n, q) with at most r points in any s-space such that K is not contained in a proper subspace. This is a slight variation on the definition of Section 3.3 of PGOFF2, where the last condition is not present. The large question is to describe all such sets. Four questions particularly are of interest.
