Generating Regular Seeds
All of the five regular polyhedra can be generated from prismatic generators with zero to two operators:
- Triangular pyramid: Y3 (A tetrahedron is a special pyramid)
- T = Y3
- O = aY3 (Rectified tetrahedron)
- C = daY3 (dual to rectified tetrahedron)
- I = sY3 (snub tetrahedron)
- D = dsY3 (dual to snub tetrahedron)
- Triangular antiprism: A3 (An octahedron is a special antiprism)
- O = A3
- C = dA3
- Square prism: P4 (A cube is a special prism)
- C = P4
- Pentagonal antiprism: A5
- I = k5A5 (A special gyroelongated dipyramid)
- D = t5dA5 (A special truncated trapezohedron)

Famous quotes containing the words regular and/or seeds:
“It was inspiriting to hear the regular dip of the paddles, as if they were our fins or flippers, and to realize that we were at length fairly embarked. We who had felt strangely as stage-passengers and tavern-lodgers were suddenly naturalized there and presented with the freedom of the lakes and woods.”
—Henry David Thoreau (1817–1862)
“The history of any nation follows an undulatory course. In the trough of the wave we find more or less complete anarchy; but the crest is not more or less complete Utopia, but only, at best, a tolerably humane, partially free and fairly just society that invariably carries within itself the seeds of its own decadence.”
—Aldous Huxley (1894–1963)
