In the Grand Gallery of the Great Pyramid the width between the third pair of overlaps, as counted up from the floor, is 22/7 royal cubits, consistent with the representation of pi as 22/7 from other features of the Grand Gallery, as detailed in my monograph.

The third pair of overlaps are marked by grooves running the entre length of the gallery, and the grooves are cut so close to the bottom of the overlaps that they were not intended to bear any weight, so may only have been of symbolic importance.

I mention this not to debate the matter, but merely to explain why I was drawn to consider the overlaps in the second antechamber of the Red Pyramid.

For the Red Pyramid, at 292/70 times the size of the Satellite Pyramid of the Bent Pyramid, the number 70 reminds us of the period of approximately 70 days when Sirius was hidden from the Egyptian sky. It may be telling that the Satellite Pyramid was not visible from the Red Pyramid.

The Satellite Pyramid is skewed at an angle extremely close to 1/pi degrees, so we should expect to find some representation of 1/pi degrees in the Red Pyramid, if this was intended.

1/pi degrees is equal to 7/22 degrees for the pi approximation 22/7, which may have been regarded as exact.

The width of the second antechamber is 7 royal cubits.

The width of 7 royal cubits is bridged by 11 pairs of laps, so that each overlap is 7/22 royal cubits.

The cotangent of 1/pi degrees is very close to 180 which leads on to the next observation...
