Really enjoying everyone's posts.
Stephen I don't have any data on this pyramid so will make some suggestions regarding yours. 'Nyuserre built a pyramid for himself at Abusir named Mensut Nyuserre,[note 16] meaning "Established are the places of Nyuserre" or "The places of Nyuserre endure".
The completed pyramid was entirely covered in fine limestone. It was about 52 m (171 ft) tall, with a base of 78.8 m (259 ft) along each side, a slope of 52 degrees and a total volume of stone of about 112,000 m3 (4,000,000 cu ft).> '
1st. The base of the pyramid 78.8m 258.53 imp feet.I have seen the base number before as it is in my essay 'From the Rollrights to Stonehenge a measure' The diameter of the Rollright stones 103.4 imperial feet ( which is 258.5 x 4 = 1034 imp feet. The perimeter of the pyramid is 10 times the diameter of the Rollrights.
The base of the Pyramid 258.5 imperial feet = 235 Indus feet 13.2 inches and the Metonic cycle is a period of 19 years during which there are 235 lunations.
The perimeter of the pyramid then is 235 x 4 = 940 Indus feet 1034 imperial feet 315.1632m.
A circle inscribed into the base of the pyramid = 738.2742737 Indus feet x 4 = 2953.097094 or 100 synodic months (29.5305/6 days).
2nd. The height about 52m = 170.60367 imperial feet and 2047.244 inches.
100 Royal cubits of 20.625 inches = 171.875 imperial feet 52.3875m and look at the number in imperial feet 10 times the width of the Kings Chamber.
