Don, surely you realize the RATIOS (not the absolute measurements) would stay consistent regardless of the size?
Whether this was a 10 meter, 500 meter, or 5,000 meter per side base, the ratios would be the same.
"1.6... 2.75... 26 degrees" all of these so called "amazing and mystifying" non-coincidences are pre-ordained by the nature of the initial shape!
Furthermore none of it proves one iota of intent.
This type of promotional post reminds me not a little of the Carnival Barker,
promising amazing and mystifying sights,
if people only pay two bits to see them...
