Soft planes and groups
William M. Kantor
Finite projective planes are constructed using groups that satisfy simple-looking conditions. The resulting projective planes include many known planes and possibly new ones, and a…
On 2-transitive sets of equiangular lines
Ulrich Dempwolff, William M. Kantor
All finite sets of equiangular lines spanning finite-dimensional unitary spaces are determined for which the action on the lines of the set-stabilizer in the unitary group is 2-tra…
Strongly regular graphs satisfying the 4-vertex condition
A. E. Brouwer, F. Ihringer, W. M. Kantor
We survey the area of strongly regular graphs satisfying the 4-vertex condition and find several new families. We describe a switching operation on collinearity graphs of polar spa…
Automorphism subgroups for designs with
William M. Kantor
Given an integer and a group of odd order, if there exists a --design and if is sufficiently large, then there is such a design whose automorphism group…
Automorphism groups of Steiner triple systems
Jean Doyen, William M. Kantor
If is a finite group then there is an integer such that for and or (mod 6), there is a Steiner triple system on points for which ${\…
Antiflag Transitive Collineation Groups
William M. Kantor
We present known results concerning antiflag transitive collineation groups of finite projective spaces and finite polar spaces.
