Okay... so after having come up with something like this:
After hours and hours of trying to make it work with 4 sites - I gave up - so instead, I worked once more on trying to decipher with a compass and ruler - and came up with this:

On your planet, try (search within 3 or 4 degrees of those just to be sure):
Longitude / Latitude
1) -64.xxxx by -31.xxxx
2) -31.xxxx by -61.xxxx
3) 64.xxxx by 31.xxxx
4) 31.xxxx by 61.xxxx
Incredibly simple? Yes.
Triangles included at all inclinations? Yes.
Line up with triangles atop the pyramid? Yes.
Dodgy numbers that make 8 bit, 16,
32 bit,
64 bit,
128 bit? Yes.
Look like something someone would do if they are obsessed with computing and AI? Yes.
Let me know if you go looking - I'm going to search all 4 locations at 11 B.
