Group theory and the 196,883-dimensional monster

An introduction to group theory, and the monster group.

Errors: *Typo on the "hard problem" at 14:11, it should be a/(b+c) + b/(a+c) + c/(a+b) = 4 *Typo-turned-speako: The classification of quasithin groups is 1221 pages long, not 12,000. The full collection of papers proving the CFSG theorem do make up tens of thousands of pages, but no one paper was quite _that_ crazy.
