Got to the end and realised that a third of the tools I used were superfluous 😉

I'm stumped.  I get 552 triangles, and I don't see the problem with my logic.  Also my picture looks very different from everyone else's.  But it is quite symmetric and seems right, even if it is hard to read.  Any thoughts would be appreciated

Process:
- Create points from the Lats and Longs
- Append fields on points (on itself)
- Append fields of points with above combined points
- Mark as collinear if either 1) all three latitudes are the same or 2) all three longitudes are all the same
- Filter out collinear records
- Filter out non-unique records (since some triangles could sit on top of each other)
- Create triangles from all sets of three points
- Clean-up
