Hypothesis of the dimensional-geometric scheme of the Nabta-Playa megalith landscape monument

The study aimed at identifying a scheme of dimensional and geometric relation-ships that could applied to famous megalithic monument called “calendar circle”, located in the archaeological area Nabta Playa. In revealed sizes, there are repetitions some prime numbers. A special role all these cases belongs number 37, which may be is connected with sequence numbers “Dome Algorithm” (1, 2, 3, 5, 7, 9, 13, 17, 21, 29, ...) , identified by author earlier having cosmographic sense. Similar regularities repeatedly earlier. particular, one can note this sense megalith Ales Stenar Sweden Sun Boat Pharaoh Cheops. results obtained article allow us state creators “small calendar circle” Playa were familiar both methods exact constructions ancient Egyptian linear measures system.
