You know how function composition works.
If then .
The “inter” function operates first.
So if then in the q permutation acts first and then the p acts.
Thus we have
hi, could anyone explain to me how you combine those? i just don't get it..
for example:
(1 2 3) o (1 2 3) = (1 2 3)
(2 1 3)__(3 2 1)___(3 1 2)
or
(p q r) o (p q r) = (p q r)
(q r p)__(r p q)___(p q r)
(ignore the underscores)
thanks!
so when you combine P and Q you have
1->2 followed by 4->1 gives us 1->2
2->4 followed by 3->4 gives us 2->1
3->1 followed by 2->2 gives us 3->3
4->3 followed by 1->3 gives us 4->4
is that right? but I just dont get it how you end up with those numbers. do you multiply, add, subtract or do something else?
