Tilings by regular polygons—II

open access: yesComputers & Mathematics with Applications, 1989
AbstractSeveral classification theorems involving highly symmetric tilings by regular polygons have been established recently. This paper surveys that work and gives drawings of these tilings—many of which were not shown in the original papers. Included are all tilings with at most three symmetry classes (orbits) of tiles, vertices or edges and those ...

Homogeneous Graphs and Regular Near Polygons

open access: yesJournal of Combinatorial Theory, Series B, 1994
AbstractWe consider a distance-regular graph having homogeneous edge patterns in each entry of its intersection diagram with respect to an edge. We call such graphs homogeneous graphs. We study elementary properties of homogeneous graphs, and we show these graphs are related deeply with regular near polygons.
