Apéry’s constant

The number

	$\\displaystyle\\zeta(3)$	$\\displaystyle=\\sum_{n=1}^{\\infty}\\frac{1}{n^{3}}$
		$\\displaystyle=1.202056903159594285399738161511449990764986292\\ldots$

has been called Apéry’s constant since 1979, when Roger Apéry publisheda remarkable proof that it is irrational [1].
