the reasoning is that 123 and 231 are same when they are in a circle for 3 element. as there are n elemtnts n copies are same so we habe n!/n or (n-1) permutations

what's your confusion? it really is the fashion of round adjustments of 12 aspects, and it truly is definitely 11! (no favor to pass more suitable). playstation : basically keep in mind that the fashion of round adjustments of n aspects is n! / n = (n-a million)! (the fashion of all accessible adjustments, divided by potential of the fashion of "rotations").
