Coefficients of the $q$ -expansion are expressed in terms of a basis $1,\beta_1,\ldots,\beta_{15}$ for the coefficient ring described below. We also show the integral $q$ -expansion of the trace form.

$f(q)$	$=$	$q + (\beta_{9} - \beta_{8}) q^{2} - \beta_{12} q^{3} + (2 \beta_{9} + 2 \beta_{3}) q^{4} + ( - \beta_{12} + \beta_{7} + \cdots - \beta_{4}) q^{5} + ( - \beta_{12} - \beta_{7} - \beta_{6}) q^{6} + ( - \beta_{2} - \beta_1) q^{7}+ \cdots + (7 \beta_{9} + 7 \beta_{8} + 7 \beta_{3} + 7) q^{98}+O(q^{100})$ q + (b9 - b8) * q^2 - b12 * q^3 + (2b9 + 2b3) * q^4 + (-b12 + b7 - b6 - b4) * q^5 + (-b12 - b7 - b6) * q^6 + (-b2 - b1) * q^7 + (2b3 + 2) q^8 + (b10 + b9 - 2b8 - b3 - b1 - 2) q^9 + (-b12 + b7 - 2b6 - b4) q^10 - 2b4 q^12 + (-b14 + b12 - b7 + b6 + b5) * q^13 + (b11 - b10 - b1) * q^14 + (b10 - 3b9 - b8 - 4b3 - 4) * q^15 - 4b8 q^16 + (b11 - b10 + 2b9 + 2b8 + 3b3 + 2b2 + b1 - 1) * q^18 + (b15 - 2b14 - b13 + b7 - b5 - b4) q^19 + (2b7 - 2b6 - 2b4) q^20 + (-b15 + 2b13 - 2b7 - b6 + b5 + 2b4) q^21 + (-2b11 + b10 - 3b9 + b2 + 2b1) q^23 + (-2b12 + 2b7 - 2b4) q^24 + (b11 + 6b8 - 2b3 - b2 + 3) * q^25 + (-b15 - b14 + b6 + b5) * q^26 + (-b14 - b12 - 3b7 - 3b6 - 2b5) q^27 - 2b10 q^28 + (b11 - 2b9 + 4b8 - 2b3 + b2 + b1 - 4) q^30 + (4b9 - 4b8 + 4b3 - 4) q^32 + (2b14 + 2b13 - b12 + b7 - 2b6 - b5) q^35 + (-2b11 - 4b9 + 2b8 + 2b1 + 4) * q^36 + (-b14 - 3b13 - b12 + b7 - b5) q^38 + (-b11 - b10 - 4b9 + b8 - b2 - b1 + 5) q^39 + (4b7 - 2b6 - 2b4) q^40 + (-3b15 + 2b14 + b13 + 2b12 - 2b4) * q^42 + (b15 - 2b14 - b13 - b12 - 2b7 - 3b6 - b5 + b4) q^45 + (-2b11 + 4b10 - 3b9 - 3b8 - 3b3 - 3) q^46 + (-4b12 - 4b6) * q^48 + 7b9 q^49 + (2b11 - b10 - b9 + 5b8 - 6b3 - b2 + 6) q^50 + (-2b15 - 2b7 + 2b5 + 2b4) * q^52 + (-b15 + 2b14 - 3b13 + 2b12 + 2b7 + 4b6 - 2b5 - 6b4) q^54 + (-2b11 - 2b2 - 2b1) q^56 + (2b11 - 2b10 - b9 - b8 - 6b3 - 2b2 - b1 + 5) * q^57 + (-3b15 + b14 - 2b13 + 2b12 - b7 + 3b6 - b5 - 2b4) q^59 + (-8b9 + 8b8 - 6b3 + 2b1 + 2) * q^60 + (b15 + b14 + 4b13 + b12 - b6 - b5 + b4) q^61 + (2b11 - b10 + 7b9 + 7b3 + 2b2 - 7) * q^63 + 8b3 q^64 + (-3b11 + b10 - 3b9 + b3 + 2b2 + 1) q^65 + (5b15 - b14 - 2b13 - 3b12 + 6b7 + b6 - b5 + b4) * q^69 + (3b14 + b13 - b12 + 3b7 - 3b6 - 3b5 - 3b4) q^70 + (2b9 - 2b8 + 2b3 - 3b2 + 3b1 - 2) q^71 + (-2b11 + 4b10 - 2b9 - 6b8 - 6b3 - 2b2 - 2b1 - 2) q^72 + (-b15 - 2b14 + 4b12 - 5b7 + 7b6 + 2b5 + 4b4) * q^75 + (2b15 - 2b14 - 2b13 + 2b12 - 4b7 + 2b6 + 2b5 + 4b4) * q^76 + (-b11 - 8b8 - 5b3 - b2 - 3b1 - 3) q^78 + (-b11 + b10 + b1 + 12) * q^79 + (4b7 - 4b6) * q^80 + (3b11 - 5b10 + 8b9 + 6b8 + 16b3 + 5b2 + 3b1) q^81 + (-b15 + 2b14 + 3b12 - b7 + b6 - 3b5) q^83 + (-2b15 + 4b14 + 2b13 + 2b12 + 2b7 + 4b6 + 2b5) q^84 + (-b14 - 3b13 + 3b12 + b7 + 2b6 - b5 - 4b4) * q^90 + (2b14 + 3b12 - b7 + 5b6 + b5 + 4b4) * q^91 + (2b11 + 2b10 + 4b2 + 2b1 - 6) * q^92 + (-b11 - 3b10 + 4b9 - 5b8 + 4b3 - b2 - 4b1 + 5) q^95 + (-4b6 - 4b4) * q^96 + (7b9 + 7b8 + 7b3 + 7) q^98
