We introduce the notion of subquadrangle regular system of a generalized quadrangle. A subquadrangle regular system of order m on a generalized quadrangle of order (s, t) is a set R of embedded subquadrangles with the property that every point lies on exactly m subquadrangles of R. If m is one half

Let c k be the smallest number of vertices in a regular graph with valency k and girth 8. It is known that c k+1 โ‰ฅ 2(1+k+k 2 +k 3 ) with equality if and only if there exists a finite generalized quadrangle of order k. No such quadrangle is known when k is not a prime power. In this case, small regul

The construction of complete lists of regular graphs up to isomorphism is one of the oldest problems in constructive combinatorics. In this article an efficient algorithm to generate regular graphs with a given number of vertices and vertex degree is introduced. The method is based on orderly genera
