These are the first of the sets of method proposed by Shadowslice. They vary in the way the corners are oriented and can be viewed as either columns first or e-slice methods
- Form the e-slice
- Orient all corners
- Permute all corners.
- Orient all edges
- Place RD or LD edges
RCa- Orient corners by correcting corner parity so it can be solved using CMLL, COLL, CLL etc.
RCb- Orient corners using the "parity" algorithm (used in Human Thistlethwaite Algorithm)
RCc- the most advanced variant, orient all corners in one algorithm (53 algorithms)
