%N Decimal expansion of log_2 (5) - log_3 (7).
%C Decimal expansion of minimal value of function gamma(n) = log_2(n+1) - log_tau(n) (sigma(n)) for n = 4, where gamma(n) is called the gamma-deviation from primality of the number n (see A236022).
%F Equals log(5)/log(2) - log(7)/log(3) = A020858 - A152565.
