• Greedy frac multiples of Catalan's constant, G: a(1)=1, Sum_{n>0} frac(a(n)*x) = 1 at x=G=A006752, where "frac(y)" denotes the fractional part of y.at n=8A080158
• Denominators of the convergents of the continued fraction for Catalan's constant L(2, chi4), where L(s, chi4) is the Dirichlet L-function for the non-principal character modulo 4.at n=12A153070
