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.

$f(q)$	$=$	$q + \beta_{14} q^{2} - \beta_{6} q^{4} + (\beta_{13} - \beta_{9}) q^{5} + (\beta_{3} + \beta_{2} - 1) q^{7} - \beta_{9} q^{8} + \beta_{11} q^{10} + (\beta_{15} - \beta_{14} + \cdots - \beta_{7}) q^{11}+ \cdots + (\beta_{15} - \beta_{13} + \cdots - \beta_{4}) q^{98}+O(q^{100})$ q + b14 * q^2 - b6 * q^4 + (b13 - b9) * q^5 + (b3 + b2 - 1) * q^7 - b9 * q^8 + b11 * q^10 + (b15 - b14 + b13 - b12 - b7) * q^11 + (-2b10 + 3b8 - 2b1 + 1) q^13 + (-b15 - b7 + b5) * q^14 - q^16 + (-b15 - b13 + b9 - b5 + b4) * q^17 + (b11 + b8 + b6 - b3 - b2 - b1 + 2) * q^19 + (-b14 - b7) * q^20 + (b10 + b2 - b1 + 1) * q^22 + (-2b15 + 2b13 - b12 + b9 - b7 + 2b5 + 2b4) * q^23 + (2b8 - 2b3 + b2 - b1 + 4) * q^25 + (b14 - 2b13 + 2b12 + 2b9 - 3b4) * q^26 + (-b10 + b8 - b1) * q^28 + (b15 + 4b14 - b9 + b7 + 4b5) * q^29 + (-b10 - 3b8 - 4b6 - 3b3 + b2 - b1 - 1) q^31 - b14 * q^32 + (-b11 - b10 - b8 - b6 + b3 - 2) * q^34 + (-2b14 - b13 + b12 + 3b9 - 2b5 - 3b4) * q^35 + (b10 + 2b3 - b1 - 1) q^37 + (b15 - b13 + 2b9 - b5 - b4) q^38 - b1 * q^40 + (-b15 + 2b14 + 2b13 - 2b12 + b7 - b4) q^41 + (2b11 - b10 + 2b8 - 2b6 - b2 - b1 + 5) q^43 + (-b15 + b14 - b13 - b12 + 2b9 - b7) q^44 + (b11 - 2b10 + 2b8 + b6 + 2b3 + b2 - b1 + 2) q^46 + (2b15 - b14 + 2b13 - b12 - 2b9 + b7 - b5 + b4) q^47 + (b11 + b8 - 2b6 - b3 - b2 - b1 + 2) q^49 + (-b15 + 2b14 - b13 + 4b9 - b7 - 2b5 - 2b4) * q^50 + (-b6 - 3b3 - 2b2 + 2) * q^52 + (b15 - b13 + 2b12 - 8b9 + 2b7 + 3b5 + 3b4) q^53 + (-2b11 - b10 - 10b6 - 4b3 + b2 - b1 - 1) q^55 + (-b13 + b12 + b9 - b4) * q^56 + (b10 + 4b8 + b6 + b1 + 4) q^58 + (-b14 + b13 + b12 - 6b9 + 5b5) * q^59 + (-b11 - 2b10 + 3b8 + 3b3 + 3b2 - 3b1 - 6) q^61 + (-b15 - 4b14 - b13 + b12 + b9 - b7 - 3b5 + 3b4) q^62 + b6 * q^64 + (3b15 - 5b14 + b13 - b12 + 3b9 + 2b7 - 7b5 + 4b4) * q^65 + (-2b10 + 4b6 + 6b3 + 2b1 - 4) * q^67 + (b12 - 2b9 + b7 + b5 + b4) q^68 + (-2b8 - 3b3 - b2 + 1) * q^70 + (-b15 + b14 + b13 - b12 + 2b9 + b7 - 2b4) * q^71 + (b10 + 5b6 + b1 - 4) q^73 + (b14 - b13 - b12 - b9 + 2b5) q^74 + (-b11 + b10 - b8 - b6 - b3 + 1) * q^76 + (b15 - 8b14 + b13 - b12 - b9 + b7 - 5b5 + 5b4) q^77 + (4b11 + 3b10 - 3b8 + 3b3 - b2 - b1 + 1) * q^79 + (-b13 + b9) * q^80 + (-b10 - b6 - b3 + 2b2 + b1 - 1) q^82 + (-b15 + b13 - b12 - 5b9 - b7 + b5 + b4) q^83 + (b11 - 2b10 - b8 + 5b6 + 3b3 - b2 - 4) q^85 + (b15 + 3b14 - b13 + b12 - 2b9 - b7 - 2b4) q^86 + (-2b11 - b10 - 2b6 + b2 - b1 - 1) * q^88 + (3b15 + b14 + 3b7 - 2b5) q^89 + (-3b11 + 2b10 - 2b8 - 3b6 - 2b3 + b2 - b1 + 10) q^91 + (-b15 + 3b14 - b13 + 2b12 + b9 - 2b7 + 2b5 - 2b4) q^92 + (b11 + 2b10 - b8 + b6 + b3 + b2 + b1) q^94 + (3b14 - b12 - 2b9 + b7 - 3b5 + 3b4) * q^95 + (b10 + b6 + b2 - b1 + 2) * q^97 + (b15 - b13 - b9 - b5 - b4) * q^98
