(e) Explain why there are infinitely many regular hyperbolic tilings, but only five regular spherical tilings, and only three regular Euclidean tilings. Problem 11. Fill in the following chart with orientation-preserving isometries, classified by a pair of reflections in two lines mand : ++ > 72 n m. nu intersect m. n disjoint R S? m, n asymptotic: min ultraparallel H?
