Mehta

Yiheng Mehta's method builds the bottom layer and the middle belt in an unusual order, so the end of the solve is the corners left (orientation, then permutation) and the edges left, each in a small algorithm set. The 6CP variant described here is the common variant.

A 1x2x3 block on the bottom left: the bottom-left corners and the edges between them, as Roux's first block but lying on the bottom. Plan it in inspection.

Place all but the last of the middle layer's edges around the block, intuitively, leaving a belt slot free.

Edge orientation and the last edge: insert the last belt edge while orienting every edge, so the rest of the solve keeps them oriented.

Orient the corners left (the bottom right pair and the top layer's) so each shows its top or bottom colour up or down.

Permute those corners, which solves the bottom layer's corners and the top's at once.

Permute the last edges, the top layer's and the bottom right, with M-slice and U turns.
