Tetrahedron: Coordinate Symmetry:
"Only the tetrahedron can be altered asymmetrically in respect to one of its faces and still remain completely symmetrical. This seems to be one of the very important properties of the tetrahedron. . . .
"The tetrahedron is a very extraordinary phenomenon in that its symmetry, its size, is not violated by accommodating two completely disparate rates of change. . . it would stay on as a volume. . . a kind of gas . . . moving around the universe, being accredited locally and accommodating all kinds of local transactions.
“The symmetry, the sixness, and the fourness are all constant.”
