Ruled quintic surfaces in $\mathrm{PG}(6,q)$

Susan G. Barwick

Vol. 17 (2019), No. 1, 25–41

We look at a scroll of PG(6,q) that uses a projectivity to rule a conic and a twisted cubic. We show this scroll is a ruled quintic surface V25, and study its geometric properties. The motivation in studying this scroll lies in its relationship with an Fq-subplane of PG(2,q3) via the Bruck–Bose representation.
