%N Decimal expansion of 1/sqrt(48).
%C Or 1/(4 sqrt(3)), which should look familiar to anyone who has studied Ramanujan's approximation for the partition numbers (see Conway and Guy). - _Alonso del Arte_, May 19 2011
%C This constant is the ratio of the area (A) to the perimeter (P) of an equilateral triangle with unit side, A/P = 1/(4 sqrt(3)). - _José de Jesús Camacho Medina_, Feb 09 2018
