%I A256573 #55 Oct 17 2016 02:26:50 %S A256573 0,14,26 %N A256573 God's number for Rubik's cube size n X n X n (quarter-turn metric). %C A256573 "God's Number" is the maximum number of turns required to solve any scramble of cube. "Quarter-turn metric" considers a 90-degree turn of any side to be a single turn, while a 180-degree turn is considered two turns. Cubes of larger size than 3 X 3 X 3 are not solved for God's number. %H A256573 Jerry Bryan, <a href="http://www.math.rwth-aachen.de/~Martin.Schoenert/Cube-Lovers/Jerry_Bryan__God's_Algorithm_for_the_2x2x2_Pocket_Cube.html">God's Algorithm for the 2x2x2 Pocket Cube</a> %H A256573 Tomas Rokicki, Morley Davidson, <a href="http://www.cube20.org/qtm/">God's Number is 26 in the Quarter-Turn Metric</a> %Y A256573 Cf.
