~~~ ~~~ [up] Subject: solution sequence

My original algorithm was:

(1) bottom corners by random twisting about

(2) bottom sides by random twisting about

(3) middle sides mostly by variants of [( r u -r -u )^2 ]^3
with extra "u" operations between the inner and outer loops

(4) top sides		mostly by variants of ( r u -r -u )^2 ( -f -u f u)^2
		with extra reps of phase 3 to swap positions around

(5) top corner position	by variations on ( r u -r -u )^2 ( r u -r -u )z
		with extra "b" operations between the major groups

(6) top corners orientation
		mostly by repitions of (gasp!)
			A = ( r u -r -u )^2
			A f A f A f A -f A -f A -f
		... which I called the "long walk"

My typical solution times with this methodology was 15-20 minutes. I suspect
If I operated ar warp speeds (like BSG) it would still be 5 minutes.

FORTUNATELY, I have developed better since then.
