Gerson: for the intermediate results to be integer, c must divide b, which is not the same as saying c must be 1 ;-))

I've written an RPL solution as well that, on EMU48 at full pelt, cranks out all 136 solutions in 30 seconds. But I'm not happy with it yet.
I used Heap's algorithm to generate all permutations - then it took 256 seconds.
Including the condition that
Code:
MOD(13*b*i + g*h*c,c*i)=0
after having selected 5 numbers reduced the timing to 30 seconds.

Cheers,
Werner
