Inside-Outing:
"Of all the Platonic polyhedra only the tetrahedra can be turned inside-out and there are three ways it can do so by single- double- and triple-bonded routes.
“In double-bonded edge-to-edge inside-outing there are pairs of diametric unfoldment of the congruent edges and the diameter unfoldment of the congruent edges and the diameter becomes the hinge of reverse positive and negative folding.”
