Abstract

We find an upper bound for the cardinality of a set of points in PG(n, q) with the property that nol of them are contained in a (l− 2)-fiat (n ≥l − 2 ≥ 0) and we treat the case of equality. We also determine all ovoids and Cameron closed sets of the regular near-hexagon related to the extended ternary Golay code.
