F2L — all 41 cases¶
The 41 cases for inserting a corner + edge pair into the front-right slot.
Read this before diving in
Learning these 41 cases by heart is the worst possible route. F2L is learned intuitively first: you understand how to pull the pair out, join it, and put it away. This page is a reference, to look up when one particular case keeps costing you time.
Every algorithm below is the shortest possible one in R, U and F: they
were found by exhaustive search, not copied. The greyed-out pieces do not matter
for the case.
