F-perm
Adjacent swap
F-perm is a PLL case on the 3x3 (Adjacent swap, medium). Algorithm: R' U' F' R U R' U' R' F R2 U' R' U' R U R' U R. Below are 3 variants with a 3D animation and a scramble to practise.
My status:don’t know
How the status is counted
Training counts the status. A case added to training gets “learning”, and “known” after 5× “correct” in a row with the timer and without hints, when the average time is within the category threshold (Settings). 2× “wrong” in the last 3 attempts or much slower times drop it back to “learning”. Daily tasks don’t change the status.
How to recognize
Block in the front left corner, headlights on the right. It’s T-perm with an added start.
