This will be running a bit slower than what has been the later weeks, the rains has gone again so I'm outside daytime now and tired at nights :)

I think we make a separate page for L3C, it is a stand alone method and it will make this page a little smaller. // Kenneth 06:51, 14 August 2010 (UTC)


I don't know if it is a good order for the 1-twist cases as is, better to group them like I did with the 3-cycles at L3C in quads where 'the same' alg can be used for each group of 4.

I do that later, first I fix the rest of the images... done. // Kenneth 09:37, 18 August 2010 (UTC)


Work area

The names for the cases are first orientation (H or pi) folled by the direction for the permutation cycle (a or b) and in the parentesis is the orientation for the placed corner (+ or -) and for the pi cases also if this corner is on the U ot the T side of the pi (For H it is only one situation).


The following four cases are mirror + inverses of the first so you only need '1 alg' for all.

Mirror to the side and inverse in diagonal.

For the following cases mirror and inverse are the same.

Mirror/inverse to the side.
