Hi all,

first thanks very much to all who responded to my previous post.

i am having trouble finding a way to do the following:

i have a list of numbers P, and i need ask the question: which members of the set are products of other members and what are their factorisations by these other members.

i notice there are graph/tree functions in mathematica to represent this sort of thing visually but im at a loss for how to implement them

anyway for an example

P = {a, b, c, d}

OUTPUT:

a -> c^2 * d
b -> c * d^2
c -> c
d -> d
