Previous name was: The sequence is: 2^8, 3^2, 5^2, 7^2, 10939058860032031^2 where 10939058860032031 is prime and where its order is an integer 337736875876935471466319632507953926400 and is equal to ((640320)^3 + 744)^2 * 70^2 where (640320)^3 + 744 is an integer value which is nearly Ramanujan's constant and 1^2 + 2^2 + 3^2 + ... + 22^2 + 23^2 + 24^2 = 70^2 which is related to the norm vector 0 used in construction of the Leech lattice.
The prime number 10939058860032031 = 2^15, 3^2, 5^3, 23^3, 29^3 + 31 Ramanujan's constant: e^(Pi*sqrt(163))= 640320^3 + 743.99999999999925 = A060295.
