3OP (3-Cycle Orientation Permutation) is a 3x3 blindfold cubing method that orients then permutes, permuting along cycles using 3-cycles. The original exposition by Olly (stiff_hands) is available at http://homepage.ntlworld.com/angela.hayden/cube/blindfold_frontpage.html
3OP, originally simply called the 3-cycle method, was used in 2003-2006 to set world records. It was the method of choice among the top blindfold cubers until the advent of more modern blindfold cubing such as M2 and BH.
