Diagonal corners
Diagonal corners is a PLL parity case on the 4x4 (trudny). Algorithm: F R U' R' U' R U R' F' R U R' U' R' F R F' U2 R' U R U' 2R2 U2 2R2 Uw2 2R2 2U2 U R' U' R U2. Below is 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
Two diagonal corners (front right and back left) are swapped, the edges are solved.
