Hawaiian Petrus is a variant of Hawaiian Kociemba that is based on the Petrus and Petrus-W methods. It starts off with a 2x2x2 block, then has 2x2x3 expansion, with the block being in DB. Then EO is done ZZ style. The 2 front F2L pairs are solved next, leaving either COLL and L5EP, OCLLDF and PLL, or OCLL and HKPLL.
