On page 15 of Math Horizons (now available online to all MAA members, I believe), the command to find the inverse of a matrix modulo n using "three popular computer algebra systems" is given. Sage is one of them. Just thought some of you might enjoy that.
Another note: apparently this is for solving an Easter Egg in Call of Duty: Black Ops. Keith Devlin has talked a lot about various gamification when it comes to math, but I'm not sure that violent of a game was what he had in mind, nor for matrix inverses mod n... or maybe it was, since it's so popular? -- You received this message because you are subscribed to the Google Groups "sage-edu" group.
