There are two distinct uniform colorings of a snub square tiling.
An alternate truncation deletes every other vertex, creating a new triangular faces at the removed vertices, and reduces the original faces to half as many sides.
If the original tiling is made of regular faces the new triangles will be isosceles.
Starting with octagons which alternate long and short edge lengths, derived from a regular dodecagon, will produce a snub tiling with perfect equilateral triangle faces.
The two vertex figures can be mixed in many k-uniform tilings.
