Coefficients of the $q$ -expansion are expressed in terms of a basis $1,\beta_1,\beta_2,\beta_3$ for the coefficient ring described below. We also show the integral $q$ -expansion of the trace form.

$f(q)$	$=$	$q + (\beta_1 - 1) q^{2} + \beta_1 q^{3} + ( - 2 \beta_1 - 2) q^{4} + (\beta_{2} + 1) q^{5} + ( - \beta_1 - 3) q^{6} + ( - 3 \beta_{3} - \beta_1) q^{7} + 8 q^{8} - 3 q^{9} + ( - 3 \beta_{3} - \beta_{2} + \beta_1 - 1) q^{10}+ \cdots + 3 \beta_{3} q^{99}+O(q^{100})$ q + (b1 - 1) * q^2 + b1 * q^3 + (-2b1 - 2) q^4 + (b2 + 1) * q^5 + (-b1 - 3) * q^6 + (-3b3 - b1) q^7 + 8 * q^8 - 3 * q^9 + (-3b3 - b2 + b1 - 1) q^10 - b3 * q^11 + (-2b1 + 6) q^12 + (b2 + 5) * q^13 + (3b3 - 3b2 + b1 + 3) * q^14 + (-3b3 + b1) q^15 + (8b1 - 8) q^16 + (-2b2 - 20) q^17 + (-3b1 + 3) q^18 + (-6b3 + 2b1) * q^19 + (6b3 - 2b2 - 2b1 - 2) q^20 + (-3b2 + 3) q^21 + (b3 - b2) * q^22 + (3b3 - 11b1) * q^23 + 8b1 q^24 + (2b2 + 9) q^25 + (-3b3 - b2 + 5b1 - 5) * q^26 - 3b1 q^27 + (6b3 + 6b2 + 2b1 - 6) q^28 + (2b2 + 28) q^29 + (3b3 - 3b2 - b1 - 3) * q^30 + (-12b3 - 8b1) * q^31 + (-16b1 - 16) q^32 - b2 * q^33 + (6b3 + 2b2 - 20b1 + 20) q^34 + 32b1 q^35 + (6b1 + 6) q^36 + (4b2 - 10) q^37 + (6b3 - 6b2 - 2b1 - 6) q^38 + (-3b3 + 5b1) * q^39 + (8b2 + 8) q^40 + (12b2 - 2) q^41 + (9b3 + 3b2 + 3b1 - 3) q^42 + (12b3 + 8b1) * q^43 + (2b3 + 2b2) * q^44 + (-3b2 - 3) q^45 + (-3b3 + 3b2 + 11b1 + 33) q^46 + (9b3 - 9b1) * q^47 + (-8b1 - 24) q^48 + (6b2 - 53) q^49 + (-6b3 - 2b2 + 9b1 - 9) q^50 + (6b3 - 20b1) * q^51 + (6b3 - 2b2 - 10b1 - 10) q^52 + (-3b2 + 13) q^53 + (3b1 + 9) q^54 + (-b3 + 11b1) q^55 + (-24b3 - 8b1) * q^56 + (-6b2 - 6) q^57 + (-6b3 - 2b2 + 28b1 - 28) q^58 + (18b3 - 6b1) * q^59 + (6b3 + 6b2 - 2b1 + 6) q^60 + (-9b2 - 1) q^61 + (12b3 - 12b2 + 8b1 + 24) q^62 + (9b3 + 3b1) * q^63 + 64 * q^64 + (6b2 + 38) q^65 + (3b3 + b2) q^66 - 36b1 q^67 + (-12b3 + 4b2 + 40b1 + 40) q^68 + (3b2 + 33) q^69 + (-32b1 - 96) q^70 + (-9b3 - 31b1) * q^71 - 24 * q^72 + (-12b2 + 62) q^73 + (-12b3 - 4b2 - 10b1 + 10) q^74 + (-6b3 + 9b1) * q^75 + (12b3 + 12b2 - 4b1 + 12) q^76 + (b2 - 33) * q^77 + (3b3 - 3b2 - 5b1 - 15) q^78 + (15b3 + 53b1) * q^79 + (-24b3 - 8b2 + 8b1 - 8) q^80 + 9 * q^81 + (-36b3 - 12b2 - 2b1 + 2) q^82 - 44b1 q^83 + (-18b3 + 6b2 - 6b1 - 6) q^84 + (-22b2 - 86) q^85 + (-12b3 + 12b2 - 8b1 - 24) q^86 + (-6b3 + 28b1) * q^87 - 8b3 q^88 + (4b2 - 146) q^89 + (9b3 + 3b2 - 3b1 + 3) q^90 + (-12b3 + 28b1) * q^91 + (-6b3 - 6b2 + 22b1 - 66) q^92 + (-12b2 + 24) q^93 + (-9b3 + 9b2 + 9b1 + 27) q^94 + (-12b3 + 68b1) * q^95 + (-16b1 + 48) q^96 + (-6b2 + 152) q^97 + (-18b3 - 6b2 - 53b1 + 53) q^98 + 3b3 q^99
