Fourier coeff's of T_0, coeff's of modular function j

[Gerald McGarvey]

Seqfans,

 From using the 'Find friends' function after noticing the term -196884 in 
A035230 ...

A035230 (Fourier coefficients of T_0) appears to be related to
A000521 (Coefficients of modular function j as power series in q=e^(2Pi i t).),
it appears that     -n * A000521(n) = A035230(n)

Also
2 * A000521(2) = A028520(3)
2 * A000521(4) + A000521(1) = A028520(4)
2 * A000521(6) = A028520(5)

A028520 is Character of extremal vertex operator algebra of rank 48.
