These algorithms [[orientation|orient]] the top layer on a [[2x2x2]]. Three variants of these [[algorithm]]s are given depending on how they affect the rest of the cube. The parts of algorithms are grouped together for easier memorization and visual distinction.<br />
# Algs which don't affect the bottom layer (suitable for both [[LBL]] and [[Ortega]]) are unmarked<br />
# Algs which affect bottom layer permutation (suitable for [[Ortega]] only) are marked with an '''O''' (these are also useful for [[EG]] 1)<br />
# Algs which mix bottom and top layers (suitable if used with [[Guimond]]-style separation) are marked with a '''G'''<br />
<br />
Below, the number of optimal moves are mentioned as a triple (x, y, z) where x is the number of optimal moves for case 1., y for case 2., and z for case 3. above. '''Note.''' A question mark means that number of optimal moves is not known. But always x ≥ y ≥ z.<br />
