Sir, Please explain the concept of finding no of arrangements and ways of beads in cases of necklace and garland. Whats about the clockwise and a
Concept of finding no of arrangements in necklace and garland cases
these are the cases of circular permutations
There are two cases of circular-permutations:-
(a) If clockwise and anti clock-wise orders are different, then total number of circular-permutations is given by (n-1)!
(b) If clock-wise and anti-clock-wise orders are taken as not different, then total number of circular-permutations is given by (n-1)!/2!
In case of beads clock-wise and anti-clockwise arrangement s are same.
