WebApr 8, 2011 · The method I use for multiplying permutations like this is to think of each cycle as a set of mappings. a (in your example) maps 1 to 3, 3 to 5, 5 to 2, and 2 to 1. Also, remember that ab means "apply b, then apply a ." So, here, we want to see where ab maps each number 1-6. Start with 1: b fixes 1 (maps it to itself) and a maps 1 to 3. WebMay 20, 2011 · Putting this into the permutation formula we get: *n= 8, r= 8 *0! = 1 *Expand out 8! If you have a factorial key, you can put it in as 8! 0! and then press enter or =.
