Johnson's solids are covered only regular polygons.
They say V.A.Zalgaller concluded that Johnson's solids contain 92 kinds of polyhedra.
But, I could put the following polyhedron with 2 squres, 8 pentagons and 40 triangles without a crack.
?Why?
Mystery of "Johnson's solid No.93" is solved by Prof.N.Mutou making full use of computer.
He say there are extremely few distortions namely about 0.01 percentage of a sidelength.
I'm surprized at his report, aren't you?
