A Classification of Semi-Translation Planes

open access: yesCanadian Journal of Mathematics, 1969
The classification of certain types of projective planes has recently been of considerable interest to both geometers and group theorists. Due in part to the current general interest in finite mathematics and the developments connecting group theory and finite geometry, the Lenz-Barlotti classification of finite projective planes (2; 10), in particular,

The translation planes of order 49

Designs, Codes, and Cryptography, 1995
The authors determine the quantity of classes of isomorphic translation planes of order 49. They report on the computer search for spreads in \(PG (3,7)\) and on classifying the spreads with the computer program NAUTY that looks for graph isomorphisms. The search results in a list of 1347 translation planes in which known planes formerly given by other

A characterization of «likeable» translation planes

Rendiconti Del Circolo Matematico Di Palermo, 1983
A translation plane of order \(q^ 2\) is said to be 'likeable' when it has kern \(GF(q)\) and when its linear translation complement contains a group of order \(q^ 2\) whose elation subgroup consists of elements, which, when the plane is constructed from a spread in \(PG(3,q)\), fix a regulus. Such planes are studied in this paper, mostly in terms of \(
