Different sources may have different conceptions of how the naming scheme would be extrapolated. So to clarify, here is left to right:
Square-1, Square-2, Square-3, Square-4
So are the Square-2, Square-3 and Square-4 mass-produced anywhere?
Here's what I think is the Na perm algorithm
(R U' L U2 R' U L') (R U' L U2 R' U L') U
Another Na perm involves collaboration with the Jb perm:
L U L' (U' R U R' F' R U R' U' R' F R2 U' R') L U' L'
Also, the Nb perm would thus be
(L' U R' U2 L U' R) (L' U R' U2 L U' R) U'
Meanwhile, He-Perm, a 53-move enormous permutation, nicknamed time-killer, sneaked into Bat-Cave and managed to make many mass produced stickered bandaged magnetic 1×1s.
