 VOP method Information about the method Proposer(s): Kenneth Gustavsson Proposed: 2010 Alt Names: LFC Variants: Guimond Method No. Steps: 3 No. Algs: 24 Avg Moves: ~18 Purpose(s): Speedsolving

VOP is an experimental three-step method for the 2x2x2 cube:

V: Make a fully solved V in the first layer of three pieces (intuitive)
O: OLFC, orient last five corners (Guimond orientation, 16 cases)
P: PLFC, permute last five corners (separation and permutation, 6+2 cases)

The +2 cases for PLFC are the two last layer permutations (J and N) that occur if the last corner of FL skips to place.

As a stand-alone method, VOP has no direct advantage or disadvantage compared to existing methods like Guimond and Ortega. It is most beneficial as an add-on for Guimond; cubers who know Guimond only need to learn the PLFC cases, plus some orientation cases in case the Guimond version destroys the V.

## The six cases of PLFC

PLFC, the 3rd step, can be recognised by the FLU, FUR, RFU, and RUB stickers. All you need to make sure of is that on the D face, the odd color is on the DFR sticker, and on the U face, the odd sticker is at the ULB position.
