hanoi 1 p1   _ p3 = move 1 disc from p1 to p3

hanoi n p1 p2 p3 = move n discs from p1 to p3 using p2 in between

The definition of the first equation is easy. To complete the second equation, you need to use hanoi again recursively.

I detailed a way to complete the second equation in my previous mail (which hopefully didn't spoil it).

Hope this helps.

Stupid error

Then it must be like this :

hanoi n 1 2 3
    | n = 1 -> moves the last disk to the goal peg
    | n > 1 -> moves all the other disk to the spare peg or to the  moves n -1 to the goal peg

So how does moving 0 disks happen? That is what your first case deals with.
