COMMENTS
| Comment from John McKay (mckay(AT)encs.concordia.ca), Jun 09 2009: This is in a paper by Lehmer from about 1945. It is related to the q-coefficients of j'/j. Added Oct 13 2010: Note j'/j = weight 2 on the modular group = E6/E4 = (1-504...)/(1+240...) = -1/1 mod 24 so j'+j == 0 (mod 24) so coefficient of q^n gives n*c(n) + c(n) = (n+1)c(n) == 0 (mod 24).
