Subject: Some simple edge processes for the 4x4 cube.

** ** ** ** SPOILER WARNING ** ** ** ** This message describes some edge processes for the 4x4 Rubic's Cube.

My collegue, Marty Hiller, came up with two simple processes

which she uses to order edges on the 4x4 cube. They are sufficient

to solve all edge permutations:

(FUl UBl FDr DBr) (r U2)^4 r (FUl UFr UBl BUr FDr) (r U2 r' U2)^3

The ^n notation means repeat the process n times.

Note that these processes probably modify the center cubes as well

but this is invisible if you have already solved the center.
