Primitive Rank 3 Groups on Symmetric Designs

AbstractWe determine the symmetric designs

The translation planes of order 49 and their automorphism groups

\mathcal{D}

A characterization of the generalized twisted field planes

which admit a group

Some subgroups of GL(n, 2) generated by involutions, II

G \leqslant Aut(\mathcal{D})

Translation planes of order 16 admitting a Baer 4-group

such that G has a nonabelian socle and is a primitiverank 3 group on points (and blocks).

Symmetric extensions of bilinear dual hyperovals

Translation planes of order 27 are classified. Various invariants play an important role in a computer search.
