K-isogonal Figures
A polytope or tiling may be called k-isogonal if its vertices form k transitivity classes.
This truncated rhombic dodecahedron is 2-isogonal because it contains two transitivity classes of vertices. This polyhedron is made of squares and flattened hexagons. |
This demiregular tiling is also 2-isogonal. This tiling is made of equilateral triangle, square and regular hexagonal faces. |

A more restrictive term, k-uniform figures is defined as an k-isogonal figure constructed only from regular polygons. They can be represented visually with colors by different uniform colorings.

Famous quotes containing the word figures:
“Families suffered badly under industrialization, but they survived, and the lives of men, women, and children improved. Children, once marginal and exploited figures, have moved to a position of greater protection and respect,... The historic decline in the overall death rates for children is an astonishing social fact, notwithstanding the disgraceful infant mortality figures for the poor and minorities. Like the decline in death from childbirth for women, this is a stunning achievement.”
—Joseph Featherstone (20th century)
