This is a classic factorial problem, so the answer to that is 6!<BR/><BR/>However, when you make the pattern circular, for each pattern that you have, the "starting number" is arbitrary. This means that 123456 = 234561 = 345612 = ...<BR/><BR/>So, each pattern with "1" as the starting number takes care of 5 others (1 pattern -> 6 patterns). So, I'd just divide by 6.<BR/><BR/>6!/6 = 5*4*3*2*1 = 120Abehttps://www.blogger.com/profile/04424868492071587450noreply@blogger.com
