Corners Last Layer [and] Edge Flip is a subset of OLLCP. CLLEF is similar to COLL in that it orients and permutes last layer corners simultaneously. However, instead of preserving LL edge orientation the algorithms flip all last-layer edges, leaving only edge permutation (EPLL). This would be used as an alternative to OLL/PLL in a regular Fridrich solve, where the OLL case has no oriented edges.
It is worth noting that CLLEF has one more case than COLL; 43 instead of 42. This is for the case where all corners are oriented and permuted but the edges still need to be oriented, leaving only edge permutation (EPLL).
