The nWo had 49 members
By my count between its inception in 96 and 2002 it had 49 members. That includes its WWF run but doesn't double over people who appeared twice (E.g Syxx/Giant in WCW/WWF respectively). It doesn't include the TNA version either. There probably might have been even more than 50. They should've ended it in 98, WCW really suffered for it over the long run.
