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.

$f(q)$	$=$	$q + (\beta_{3} + \beta_1 + 1) q^{2} + 3 \beta_1 q^{3} + (3 \beta_{3} - 3 \beta_{2} + 7 \beta_1) q^{4} + ( - 2 \beta_{3} - 2 \beta_1 - 2) q^{5} + ( - 3 \beta_{2} - 3) q^{6} + ( - 5 \beta_{2} - 41) q^{8}+ \cdots + (90 \beta_{2} - 72) q^{99}+O(q^{100})$ q + (b3 + b1 + 1) * q^2 + 3b1 q^3 + (3b3 - 3b2 + 7b1) q^4 + (-2b3 - 2b1 - 2) * q^5 + (-3b2 - 3) q^6 + (-5b2 - 41) q^8 + (-9b1 - 9) q^9 + (-6b3 + 6b2 - 30b1) q^10 + (10b3 - 10b2 - 8b1) q^11 + (-9b3 - 21b1 - 21) * q^12 + (-12b2 + 14) q^13 + (6b2 + 6) q^15 + (-27b3 - 55b1 - 55) * q^16 + (-2b3 + 2b2 - 2b1) q^17 + (-9b3 + 9b2 - 9b1) q^18 + (24b3 - 44b1 - 44) * q^19 + (26b2 + 98) q^20 + (-12b2 - 132) q^22 + (34b3 - 20b1 - 20) * q^23 + (-15b3 + 15b2 - 123b1) q^24 + (12b3 - 12b2 - 65b1) q^25 + (-10b3 - 154b1 - 154) * q^26 + 27 * q^27 + (24b2 - 138) q^29 + (18b3 + 90b1 + 90) * q^30 + (72b3 - 72b2 - 16b1) q^31 + (-69b3 + 69b2 - 105b1) q^32 + (-30b3 + 24b1 + 24) * q^33 + (6b2 + 30) q^34 + (27b2 + 63) q^36 + (36b3 + 106b1 + 106) * q^37 + (4b3 - 4b2 + 292b1) q^38 + (-36b3 + 36b2 + 42b1) q^39 + (102b3 + 222b1 + 222) * q^40 + (-30b2 - 210) q^41 + (-48b2 + 212) q^43 + (-76b3 - 364b1 - 364) * q^44 + (18b3 - 18b2 + 18b1) q^45 + (48b3 - 48b2 + 456b1) q^46 + (-68b3 + 40b1 + 40) * q^47 + (81b2 + 165) q^48 + (41b2 - 103) q^50 + (6b3 + 6b1 + 6) * q^51 + (-78b3 + 78b2 - 406b1) q^52 + (4b3 - 4b2 - 554b1) q^53 + (27b3 + 27b1 + 27) * q^54 + (24b2 + 264) q^55 + (-72b2 + 132) q^57 + (-90b3 + 198b1 + 198) * q^58 + (-116b3 + 116b2 + 460b1) q^59 + (78b3 - 78b2 + 294b1) q^60 + (-72b3 + 250b1 + 250) * q^61 + (-128b2 - 992) q^62 + (27b2 + 631) q^64 + (20b3 + 308b1 + 308) * q^65 + (-36b3 + 36b2 - 396b1) q^66 + (108b3 - 108b2 + 20b1) q^67 + (26b3 + 98b1 + 98) * q^68 + (-102b2 + 60) q^69 + (-30b2 + 492) q^71 + (45b3 + 369b1 + 369) * q^72 + (12b3 - 12b2 + 530b1) q^73 + (178b3 - 178b2 + 610b1) q^74 + (-36b3 + 195b1 + 195) * q^75 + (-108b2 - 700) q^76 + (30b2 + 462) q^78 + (108b3 + 232b1 + 232) * q^79 + (218b3 - 218b2 + 866b1) q^80 + 81b1 q^81 + (-270b3 - 630b1 - 630) * q^82 + (96b2 + 924) q^83 + (-12b2 - 60) q^85 + (116b3 - 460b1 - 460) * q^86 + (72b3 - 72b2 - 414b1) q^87 + (-420b3 + 420b2 - 372b1) q^88 + (142b3 - 254b1 - 254) * q^89 + (-54b2 - 270) q^90 + (-280b2 - 1288) q^92 + (-216b3 + 48b1 + 48) * q^93 + (-96b3 + 96b2 - 912b1) q^94 + (-8b3 + 8b2 - 584b1) q^95 + (207b3 + 315b1 + 315) * q^96 + (276b2 + 266) q^97 + (90b2 - 72) q^99
