If anyone knows this move sequence please tell me. thank you. -Harlequin [Moderator's note: It is impossible to perform an odd permutation of the edges of the Megaminx, because 5-cycles are even. This is not the same situation as with Rubik's cube, where it is possible to perform an odd permutation of the edges if an odd permutation of the corners is also performed. Did they use the same color for more than one face of the Megaminx? Is there another way to get fooled? --Dan]
