If locking tabs are used in assembling the pyramids, neither of these models will need any glue. If locking tabs are not used, a small amount of glue will be needed to assemble the four module pyramids. Triangle Edge Module by Lewis Simon and Bennett Arnstein Unfold mountain crease made in FIG. 1. Crease A on entering module lines up with crease B on receiving module. Crease B on entering module lines up with mountain crease along diagonal seam on receiving module. This module makes polyhedra with flat equilateral triangle faces.

Fullerene is made up of sixty carbon atoms arranged as on the corners of a truncated icosahedron which is roughly the shape of a soccer ball. Crystallography: Many crystals take the shape of polyhedra. For example, fluorite is octahedral; sugar, gold and copper are cubic.
