COMMENT

T_8 is the unique weight = -6 normalized meromorphic modular form for SL(2,Z) with all poles at infinity.

FORMULA

Gen. fcn. = G_6/Delta (in Siegel's notation.)

EXAMPLE

T_8 = 1/q - 480 - 28404 q - ....

PROGRAM

(PARI) {a(n)=local(A); if(n<-1, 0, n++; A=x*O(x^n); polcoeff( sum(k=1, n, -504*sigma(k, 5)*x^k, 1+A)/eta(x+A)^24, n))} /* Michael Somos Oct 30 2006 */
