Related Polyhedra and Tilings
The planar tilings are related to polyhedra. Putting fewer triangles on a vertex leaves a gap and allows it to be folded into a pyramid. These can be expanded to Platonic solids: five, four and three triangles on a vertex define an icosahedron, octahedron, and tetrahedron respectively.
This tiling is topologically related as a part of sequence of regular polyhedra with Schläfli symbols {3,n}, continuing into the hyperbolic plane.

Famous quotes containing the word related:
“So-called “austerity,” the stoic injunction, is the path towards universal destruction. It is the old, the fatal, competitive path. “Pull in your belt” is a slogan closely related to “gird up your loins,” or the guns-butter metaphor.”
—Wyndham Lewis (1882–1957)
