I believe Eric Brok has something like this on his site.

Part of the difficulty of creating these triangles is how you make the
angles...for example, with Technic beams, you have to measure from the
center of one end hole to the center of the other. If you're using 1x2
plate hinges, the lengths of the sides are increased, etc.

I was taught Pythagorean Triples--same difference.

Did you add an algorith to remove multiples? (I saw that 6,8,10 10,24,26
and others are missing.)

I'm pretty sure it would be. After all, LEGO parts are slightly
flexible, so you could probably have a greater error margin.
Thanks for your efforts!
