Gb Perm

Adjacent corner swap: Two neighbouring corners swap (plus edges); comes up 1 in 18 solves.

Algorithms

1. R' U' R y R2 u R' U R U' R u' R2 reads as Extract (inverse) · y R2 u · Insert (inverse) · U' R u' R2
2. R' U' R U D' R2 U R' U R U' R U' R2 D reads as Righty (inverse) · D' R2 U R' U · ZagZag · R2 D
3. F' U' F R2 u R' U R U' R u' R2 reads as F' U' F R2 u · Insert (inverse) · U' R u' R2
