516 on the money.

 

Sneaky @JoeM  didn't put all the points in a perfect straight line which made for some fun....

Turns out that the create polygon actually takes care of most of the heavy lifting for you - any truly colinear points don't actually correctly resolve into a polygon so you have an easy check.

Looking forward to working through other folk's solutions!

I thought this was going to be way simpler than it turned out to be, that final filter is tricky

This challenge helped me to learn that spatial point ordering within a triangle influences the outcomes of convex hull versus sequence polygon

the sequence polygon results in three times as many records after using the unique tool, ergo they aren't uniquethe sequence polygon results in three times as many records after using the unique tool, ergo they aren't unique

This was a fun one, got a full match to the 516 triangles. Keen to see how everyone has implemented logic for colinearity.
