We study incidence structures with a sharply point transitve group of automorphisms (i.e., incidence groups), and state conditions for the possibility to reconstruct the lines from information about the action of the group. This treatment generalizes the familiar description of translation planes. It also includes H. Groh's characterization [Abh. Math.

Finite Galois arithmetics are well-known; finite geometries however, though more interesting to the amateur, have not really acquired professional status and do not appear to any great extent in standard works. The following example arose from a chance remark in Mathematics for T. C. Mits, by L. R. and H. G.

The Geometry of Point Reflections and Quasigroups
Results in Mathematics, 2020This is a survey of results from the rich theory of medial and more general quasigroups and its close connection with the geometry of point-reflections. The emphasis is on questions regarding the simplest axiomatization, in the sense of the minimal number of variables appearing in the identtties, on dependence or independence of axioms, and on ...

The following paragraphs have been assembled in consequence of my reading Dr. Cundy’s note on 25-point geometry. Towards the end of it, apparently mindful of the adjunction of a “ line at infinity ” to the Euclidean plane, he adjoins a line to the 25-point plane and so obtains a geometry of 31 points. Here I reverse this procedure : I start with the 31-
