Subject: Christman CrossGreetings, to those who are still on this list!!
I have discovered a rather fast method of doing the Christman
Cross. It can be done in 22 quarter twists, and I think it can be
optomized down into 20. When I ask somebody what the current
representation for transforms is, I will send the HOW along.
((NOTE: This means the Plummer Cross can be done in 44 QTwists))
((((REMARK: For those who count Half Twists [[**sigh**]] as one
MOVE, this algorithm is a mere 16 MOVES))))
