This article considers an Fq-conic contained in Fq-subplane of PG(2,q3), and shows that it corresponds to a normal rational curve the Bruck-Bose representation PG(6,q). The main result characterises which curves PG(6,q) correspond via Fq-conics PG(2,q3). interest are called 3-special, property describes how extension meets transversal lines regular 2-spread representation. proof uses geometric ...
