Catalan's Constant

In mathematics, Catalan's constant G, which occasionally appears in estimates in combinatorics, is defined by

where β is the Dirichlet beta function. Its numerical value is approximately (sequence A006752 in OEIS)

G = 0.915 965 594 177 219 015 054 603 514 932 384 110 774 …

It is not known whether G is irrational, let alone transcendental.

Catalan's constant was named after Eugène Charles Catalan.

    It’s better that it should make you sick than that you don’t eat it at all.
    Catalan proverb, quoted in Colman Andrews, Catalan Cuisine.

    For centuries the death penalty, often accompanied by barbarous refinements, has been trying to hold crime in check; yet crime persists. Why? Because the instincts that are warring in man are not, as the law claims, constant forces in a state of equilibrium.
