FORMULA

It is conjectured that L=0.5432589653429767...=Gamma(1/3)*Gamma(5/6)/Gamma(1/6)


MATHEMATICA

Gamma[1/3]*Gamma[5/6]/Gamma[1/6] // RealDigits[#, 10, 104]& // First (* JeanFrançois Alcover, Feb 25 2014 *)


PROG

(PARI) { default(realprecision, 1080); x=gamma(1/3)*gamma(5/6)/gamma(1/6); d=0; for (n=0, 1000, x=(xd)*10; d=floor(x); write("b081760.txt", n, " ", d)); } [From Harry J. Smith, Apr 13 2009]
