H-perm
Edges only
H-perm is a PLL case on the One-handed 3x3 (Edges only, easy). Algorithm: R2 U2' R U2' R2 U2' R2 U2' R U2' R2. 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
On each side the edge is the opposite colour of the corners. It’s enough to see this on two sides.
