In this paper we investigate qz/4-sets of type (O,q/4,q/2) in projective planes of order q=O(mod4). These sets arise in the investigation of regular triples with respect to a hyperoval. Combinatorial properties of these sets are given and examples in Desarguesian projective planes are constructed.
Spread sets of projective planes of order q3 are represented as sets of q3 points in ~ ~ AG (3, q3). A line through the origin in .d can be interpreted as a space ~o ~ AG(3, q), and the spread set induces a cubic surface ~ in .do. If the projective plane is a semifield plane of dimension 3 over its
