Title: The 600-cell

Speaker: Chris Godsil Affiliation: University of Waterloo Room: MC 5479

Abstract:

If d ≥ 5, then in Rd there are exactly three regular polytopes (simple, hypercube, dual hypercube). If d = 3 we have the icosahedron and the dodecahedron in addition. If d = 4, there are again two exceptional regular polytopes, the so-called 120-cell and 600-cell.
