D80-D89

Description

A novelty dice set! D80, D81, D82, D83, D84, D85, D86, D87, D88 and last but not least, D89. All these dice are not perfectly fair because they pretty much scientifically cannot be fair, however, all faces of these polyhedra have nearly identical areas, all of the dihedral angles between adjacent faces are nearly identical and the polyhedron has an inscribed sphere. What's more, the pyramids formed by each face and the model's center have nearly the same volume. These four constraints make sure that these dice are more than 99% fair. However, for most faces there are no opposite pairs because it is impossible for odd-faced polyhedra and is nearly impossible even for even-faced polyhedra of this family. Have fun!
