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:
“The solid and well-defined fir-tops, like sharp and regular spearheads, black against the sky, gave a peculiar, dark, and sombre look to the forest.”
—Henry David Thoreau (1817–1862)
“If you can look into the seeds of time,
And say which grain will grow and which will not,
Speak then to me.”
—William Shakespeare (1564–1616)
