(a,b,c) is called friendly, if each

number is equal to the product of

the other 2. How many friendly

triples are there?

Details and assumptions

The numbers need not be equal to

each other.

The numbers need not to be

pairwise distinct (which

means that no two of them

are the same). I got 31 but it isn't

right ...
