Sequential numbers in the architecture of the Great Pyramid appear to be 7, 14, 28 and 5.5, 11, 22, together with multipliers of 4 and 10. These numbers reflect an angle of slope of the Great Pyramid as 51°50'35 (51.843°) differing fractionally from the observed 51.844° and the height: half base = 1.27272' (˜vF).
