A translation plane of order 81 and its full collineation group

open access: yes, 1984
In this paper a new translation plane of order 81 is constructed. Its collineation group is solvable and acts on the line at infinity as a permutation group K which is the product of a group of order 5 belonging to the center of K with a group of order ...

Remarks on the concepts of affine transformation and collineation in teaching geometry in teachers’ training college [PDF]

open access: yes
In [11] and [12] (textbooks for teachers’ training colleges written by B. Pelle) isometry and similarity are defined not in the classical way but as a product.

Projective planes with a large quasi-regular collineation group

open access: yes, 2003
London Mathematical Society Lecture Note Series n. 307 Let be a finite projective plane of order n, and let G be a large abelian (or, more generally, quasiregular) collineation group of ; to be specific, we assume |G| > (n2 + n + 1)/2.
