Coefficients of the $q$ -expansion are expressed in terms of a basis $1,\beta_1,\ldots,\beta_{11}$ for the coefficient ring described below. We also show the integral $q$ -expansion of the trace form.

$f(q)$	$=$	$q + (\beta_{10} - \beta_{6} - \beta_{4} - \beta_1) q^{2} + ( - \beta_{10} - \beta_{2}) q^{3} + ( - \beta_{10} - \beta_{9} - \beta_{8} + \cdots + 1) q^{4} + ( - \beta_{11} - \beta_{7} + \cdots -
