Hello,

-I didn't actually invent them myself (I wish I had that capacity though). I just figured out what I wanted the cube to look like, so that perfoming twice the sequence that got us there would produce the desired outcome. Then I used "Cube Explorer" to find the algorithms that would generate the cube that I had constructed. I don't know if you've had the joy of working with 'cube explorer' before, but I've found it to be extremely useful. You can download this at www.home.t-online.de/home/Kociemba/cube.htm or, as I usually do, you can follow the link off of Jessica Fridrich's web page.

U' L2 R2 D' F2 D' L' R F U2 F' L' R U'

twice for a edge pair flip, or this classic:

L' F2 L U' B2 U

twice for a corner pair twist."

-you are right. I was working with sequences that were only allowed to flip/twist pieces if they also moved them. With this restriction my statement is correct...but I was wrong in assuming that this covered all possible sequences, so I was forgetting that I'd restricted myself....I'm feeling a little ignorant at this point.
