%N A182523 Rademacher's sequence C_{011}(N) times (2n)!, where C_{011}(N) is the coefficient of 1/(q-1) in the partial fraction decomposition of 1/((1-q)(1-q^2)...(1-q^N)).
%C A182523 Hans Rademacher conjectured that C_{011}(N) converge to -0.292927573960. This conjecture is false.
%C A182523 Named after the German-American mathematician Hans Adolph Rademacher (1892-1969). - _Amiram Eldar_, Jun 22 2021
