      The great pyramid appears to have an octagonal base.

      Not like a full equitable octagon, but four faces each split via a small concavity.

      I think the attached picture is the original one an RAF pilot took at dusk when he noticed that the shadow wasn’t uniform across the face of one side.

      I know the 8 sides are contested, some people say the concavity is an optical illusion.

          Egyptologists are conservative and won’t allow any measurements of practically anything anymore.

          No looking at the sphinx shafts/cavities (there’s an entrance up top), no tomb inspections, no measuring a bunch of stuff.

          They even paved over a bunch of shafts for “restoration”.

          Every time you hear about a new radar scan or whatever, it took years to get through the bureaucracy.

          The collected sourced pictures appear to be accurate at any rate.

            One could do some photogrammetry and then analyze the 3d mesh. It only requires taking multiple photos from different angles. Might even be able to get something going from online photos, provided you match the time of day for the entire set…
