Week 5 (October 20)
Project AssignmentLecture: Counting the number of permutations of a Rubik's Cube (using permutation and orientation)
Guest: Lars Petrus, explaining the history and details of the Petrus method.
Week 6 (October 27)
Guest: Professor Bump, giving an introduction to group theory and the cube: the definition of a group, permutations, cycles, parity, commutators, conjugates, cosets.Various short topics
4LLL: T-Perm and Y-Perm.
Homework:
Since we talked about a lot of the ideas in class, I'd like you to take a look at 3 famous pages: commutators, as well as the 3OP blindsolving method and the new, popular M2 method:And once you've looked at them, just send me a few sentences telling me what you think/understand: Is something not making sense at all? Do you see some brilliant connections? Can you apply what you read?
Week 7 (November 3)
Guest: Tom Rokicki, talking about computer cubing (Slides) Demonstration: Computer SoftwareHomework:
Work on your project.Recommended: Especially if your project involves learning something to get faster, you should look at timers and programs, executable and web-based.
I highly recommend CCT, qqTimer, and Ryan Heise's simulator.
