The previous world, of 143000 generations, is characterized by
15!/2^8 + 143000*29 = 71500^2
The 143000 generations, of 29 years, include the period of Australopithecus, Homo Erectus, Homo Heidelbergensis, Homo Neanderthalensis, Denisova Hominins, Homo Sapiens.
Even nicer is the equation
15!/2^10 + 35750*29 = 35750^2
suggesting that special attention was in place in the last 35750 generations.
Anyway, G-d Himself created Man.
