%N A160515 Decimal expansion of the integer (640320^3 + 744)^2 * 70^2 = 337736875876935471466319632507953926400.
%C A160515 640320^3 + 744 is an integer that is very close to Ramanujan's constant e^(Pi*sqrt(163)) = 640320^3 + 743.99999999999925 and 70^2 is related to the norm vector 0 of the hyperbolic version of the Leech lattice since 1^2 + 2^2 + 3^3 + ... + 22^2 + 23^2 + 24^2 = 70^2.
%C A160515 337736875876935471466319632507953926400 = 2^8*3^2*5^2*7^2*10939058860032031^2 and 10939058860032031 is a prime number that can be decomposed to 2^15*3^2*5^3*23^3*29^3 + 31.
