Regular Skew Polyhedron
In geometry, the regular skew polyhedra are generalizations to the set of regular polyhedron which include the possibility of nonplanar faces or vertex figures.
These polyhedra have two forms: infinite polyhedra that span 3-space, and finite polyhedra that close into 4-space.

Famous quotes containing the word regular:
“My attitude toward punctuation is that it ought to be as conventional as possible. The game of golf would lose a good deal if croquet mallets and billiard cues were allowed on the putting green. You ought to be able to show that you can do it a good deal better than anyone else with the regular tools before you have a license to bring in your own improvements.”
—Ernest Hemingway (1899–1961)
