2x2
Ortega, CLL and EG
Ortega (Varasano)
A face, the opposite face, then both layers' permutation: 13 algorithms.
First face → OLL → PBL · 13 cases
CLL
A first layer, then the whole last layer in one algorithm.
First layer → Last layer · 40 cases
EG (Erik-Gunnar)
A face only, then one algorithm for everything else: CLL, EG-1 and EG-2.
First face → Last layer · 120 cases
