Hi Mark,

The Bent Pyramid had a base of 362 cubits according to both Petrie and Dorner. The platform that was built around the pyramid just above the base created an effective pyramid of 360 cubits as the horizontal platform was built over 1 cubit of the base width. This can be confirmed by Petrie's maeasurements and diagram of the pavement.

Accordingly the satellite pyramid is either 99 or 100 cubits away from the pyramid depending whether you are talking about the base or the platform. As a part of the base was hidden beneath the platform it would suggest that the 100 cubits applied.

Petrie also stated that the plaform extended 20 or 30 inches beyond the edge of the base. If it was 30 inches this would be about 1.5 cubits. The total platform width would then be 362 + 1.5 + 1.5 which comes to 365.

The Bent pyramid was built soon after the Step pyramid which displayed several calendar symbolisms and we might expect some calendar symbolism in the design of the Bent also.

A straight base edge of 360 cubits may be symbolising the 36 decans of 10 days which measured the year, with one day represented by 1 cubit.

The platform extensions of 5 cubits may be seen as the 5 epagomenal days.

The perimeter of the platform was 365 x 4 which is 1460 which can be seen as the sothic cycle of 1460 years.

Regarding your proposal that the perimeter of the bend of 25,920 cubits represents the precession cycle of 25,920 years this is very interesting but a hard one to accept in that the cycle could only be measured if changes over thousands of years had been monitored and a circle was recognised, as was done later by Hipparchus

I have a idea to offer on this and will write it up shortly.
