Excluding a precise list of groups like alternating, symmetric, cyclic and dihedral, from 1st year algebra (§7.2.3), we expect there are only finitely many monodromy groups of primitive genus 0 covers. Denote this nearly proven genus 0 problem as Problem 2 . We call the exceptional groups 0-sporadic. Example: Finitely many Chevalley groups are 0-sporadic. A proven result: Among polynomial 0-spo...

I should warn readers that some of Trivers’ description of interactions with women do not comport with contemporary ideas about political correctness. On the other hand, he rails against Jamaican treatment of homosexuals and has been an outspoken proponent of gay rights on the island. Robert Trivers is a complex individual who, as the book reveals, has lived a much more turbulent life than most...

[ESU] Tiling space and slabs with acute tetrahedra, with David Eppstein and Alper Üngör. We show it is possible to tile three-dimensional space using only tetrahedra with acute dihedral angles. We present several constructions to achieve this, including one in which all dihedral angles are less than 78 degrees, another which tiles a slab in space. Several of our examples come from tetrahedrally...
