Let M = round(Pi^163) then M = d_1 * d_2 = 529774009007567162534610269 * 2048040786788341811748262618745700181736326274373241213. M = a^2 + b^2 = 32668814662851590790630599022445863401819 * 4212757618487543121739337171097252478756. s(M), the sum of proper divisors of M, equals 2048040786788341811748262619275474190743893436907851482. phi(s(M)) = 620618102278114214685524246515921764248373667313633800. s(M)/phi(s(M)) = 3.300001690686367432257271232... (phi(m) is the totient function).
