A note on representing dowling geometries by partitions

Frantisek Matus, Aner Ben-Efraim

Research output: Contribution to journalArticlepeer-review


We prove that a rank 3 Dowling geometry of a group H is partition representable if and only if H is a Frobenius complement. This implies that Dowling group geometries are secret-sharing if and only if they are multilinearly representable.
