2GLL

The document outlines the 2GLL (Two-Generator Last Layer) algorithms for solving the last layer of a cube, specifically focusing on cases where the corner permutation (CP) is already solved. It includes various algorithm sequences categorized by their efficiency and average move counts, along with specific notation for each algorithm. Prerequisites for understanding these algorithms include knowledge of COLL and familiarity with EPLL and ZBLL subsets.
