Two-generator last layer (2GLL)
Niche
Since the 2000s
Every case cross-checked
Edges oriented and corners permuted: the whole last layer, R and U algorithms first: 84 cases.

Source: Derived 2026-10-29 from zbll-t, zbll-u, zbll-l, zbll-h, zbll-pi, zbll-s, zbll-as, pll: the cases the engine finds match the rule "corners-permuted", with their sources' definitions and algorithms, each algorithm re-checked against this set's goal. More algorithms turning only R and U from Cubemuch, https://cubemuch.com/en/algs/3x3/zbll/, each matched to its case by the engine. Every algorithm shown was checked by the logic engine; rejected ones are listed in docs/db-exclusions.md.
