comment Composition vs serial assignment, which performs better?
@march I haven't tried it by composing everything together. It would take me a very long time. So I thought I would ask on here before starting... (and besides if I tried it, I would get the answer; so why would I bother asking?)

I'd never heard of PermutationCylces, PermutationGroup and GroupElements. Very handy functions!

comment Is there an easy way to let mathematica print out every Erfc and InverseErfc as F and F^{-1}
I would like to point you to a similar question I wrote about a different function Dot. I hope it will help: mathematica.stackexchange.com/questions/63147/…
