An object named for this man that has 336 symmetries can be constructed by tiling a triple torus with 24 heptagons.
An object named for this man that has 336 symmetries can be constructed by tiling a triple torus with 24 heptagons. That surface named for him is also described by the quartic x-cubed y plus y-cubed z plus z-cubed x equals zero. This mathematician proposed studying the invariants of a manifold and its transformation group in the Erlangen Program. The connected sum of two projective planes is named for this man, who also lends his name to Z2 times Z2. A shape named for this man is the only exception to the Heawood Conjecture. The smallest non-cyclic group is called his four-group. For 10 points, name this German mathematician, the namesake of a non-orientable surface which can be formed by joining two Mobius strips together, his "bottle."
