Hole Copy Sticks out

“Nopert” means non-Rupert. The 8-vertex stellated tetrahedron is P_11/20. The 60-vertex rhombicosidodecahedron follows. C₁₁ is the Undecanope, an 88-vertex Nopert polyhedron (paper). C₁₅ is the 90-vertex Noperthedron. The pass ratio is the largest scale at which the copy's shadow fits inside the hole.
