$q$ -expansion

gp: mfcoefs(f, 20)

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.

$f(q)$	$=$	$q - \beta_{13} q^{2} + \beta_1 q^{3} - q^{4} + ( - \beta_{8} - \beta_{6} - \beta_{3} + \cdots - 1) q^{5} + \beta_{6} q^{6} + ( - \beta_{7} - \beta_{6} + \beta_{4} + \cdots + 1) q^{7} + \beta_{13} q^{8}+ \cdots + ( - 3 \beta_{15} + 2 \beta_{14} + \cdots + \beta_1) q^{99}+O(q^{100})$ q - b13 * q^2 + b1 * q^3 - q^4 + (-b8 - b6 - b3 + b2 - 1) * q^5 + b6 * q^6 + (-b7 - b6 + b4 - b2 + 1) * q^7 + b13 * q^8 + (b5 + b4 + 2b2 - 3) q^9 + (-b14 + b13 - b12 - b11 + b10 + b1) * q^10 + (b15 - b14 + b13 + b11) * q^11 - b1 * q^12 + (b8 + 2b7 - b5 + b2 - 3) q^13 + (-b12 - b11 - b10 + b9 + b1) * q^14 + (b15 - b14 - 2b12 - b11 - 3b10 - b1) * q^15 + q^16 + (-b14 - b13 - b12 + b9 - b1) * q^17 + (-b15 + b13 - b12 + b10 + b9) * q^18 + (-b15 + 2b13 - b12 - 2b11 + b9) * q^19 + (b8 + b6 + b3 - b2 + 1) * q^20 + (b15 - 4b13 + b10 - 2b9 + b1) * q^21 + (-2b7 + b5 + b3 - b2 + 2) q^22 + (b8 - b7 - b4 + b3 + 2) * q^23 - b6 * q^24 + (b8 + 2b7 + b6 + 2b4 + 2b2 + 3) q^25 + (b15 + b13 + b12 + 2b11) q^26 + (b15 - 2b13 + b12 - b11 + 3b10 + b9 - b1) * q^27 + (b7 + b6 - b4 + b2 - 1) * q^28 + (2b8 - b6 + b5 + b3 + 2b2 - 4) * q^30 + (b15 - 2b13 - b12 + 3b11 - b9) * q^31 - b13 * q^32 + (5b8 - 3b7 - b6 + b5 + b4 - 5b2 + 2) q^33 + (-b7 - b6 - b4 + b3 - b2) * q^34 + (-4b8 - 4b7 - 2b6 - 2b5 - b3 + b2 + 1) * q^35 + (-b5 - b4 - 2b2 + 3) q^36 + (b15 - b14 + b13 + 2b11 - b10 - b9 - b1) q^37 + (2b7 - b5 - b4 + b2 + 1) q^38 + (b15 + b14 - 2b13 - b12 + 4b11 - b9 - 2b1) q^39 + (b14 - b13 + b12 + b11 - b10 - b1) * q^40 + (b13 - 2b11 + 2b9) * q^41 + (2b8 + b6 + b5 + 2b4 - b2 - 5) * q^42 + (-b14 - 4b12 - b9) q^43 + (-b15 + b14 - b13 - b11) * q^44 + (5b8 - 3b7 + 2b6 + b4 - b3 - 2b2 + 4) * q^45 + (b14 - 3b13 + 2b12 + 2b10 - b9) q^46 + (b14 - b13 - b12 + 5b11 - 3b10 - 2b9 - b1) q^47 + b1 * q^48 + (-4b8 - b7 - b6 - b4 - b3 + 4b2 + 3) * q^49 + (-6b13 - b12 + 2b11 - b10 + 2b9 - b1) q^50 + (4b8 - b7 - 7b2 + 8) * q^51 + (-b8 - 2b7 + b5 - b2 + 3) q^52 + (3b8 - b7 + b6 - b5 + b4 - b3 + b2 - 1) q^53 + (-2b8 + b7 - b6 + b5 - b4 - b2 + 1) q^54 + (-2b15 + b14 - 3b13 - b12 + 5b11 - 5b10 - 2b9 - b1) q^55 + (b12 + b11 + b10 - b9 - b1) * q^56 + (-b8 + 3b7 - 2b6 - b5 + b2) * q^57 + (b8 - b7 + b6 - b5 + b4 - 2b3 + b2) q^59 + (-b15 + b14 + 2b12 + b11 + 3b10 + b1) * q^60 + (b13 + b12 + 2b11 - 5b10 - 2b9 - b1) q^61 + (2b8 - 3b7 + b5 + b4 - 4b2) q^62 + (-b8 - 5b7 + 3b6 + b5 + b4 + 2b3 + 4b2 - 2) * q^63 - q^64 + (-4b8 + b7 + 3b6 + 2b5 - 3b4 + b3 - 6b2 + 4) q^65 + (-b15 - 2b13 + 4b12 - 3b11 + 2b10 + b9 + b1) * q^66 + (2b7 - 2b5 + b3 + 2b2 - 6) q^67 + (b14 + b13 + b12 - b9 + b1) * q^68 + (-2b15 + b14 - 2b13 + 4b12 - b11 + 2b9 + 2b1) q^69 + (2b15 - b14 + 2b13 - 4b12 - 5b11 + 2b10 + 2b1) * q^70 + (3b8 + 2b7 - b6 - 2b3 - 4b2 + 2) * q^71 + (b15 - b13 + b12 - b10 - b9) * q^72 + (b15 - b12 - b11 - b10 - b9 + 2b1) q^73 + (b8 - 3b7 - b6 + b5 + b4 + b3 - b2 + 1) q^74 + (2b15 + b14 - b13 - 2b12 + 4b11 + 6b10 - b9 + 3b1) q^75 + (b15 - 2b13 + b12 + 2b11 - b9) * q^76 + (4b15 + 4b13 - b12 + 3b11 - b10 - 3b9 - b1) * q^77 + (2b8 - 3b7 - 2b6 + b5 + b4 - b3 - 5b2 + 1) * q^78 + (-3b15 + b13 - 2b12 - b11 - b10 + 3b9 - b1) q^79 + (-b8 - b6 - b3 + b2 - 1) * q^80 + (b4 - 2b3 - 2b2 + 2) * q^81 + (-2b8 + 2b7 - 2b4 + 2b2 + 1) * q^82 + (-2b8 + 7b7 - b6 - 3b5 - 3b4 - b3 + 8b2 - 3) q^83 + (-b15 + 4b13 - b10 + 2b9 - b1) * q^84 + (-2b15 - b14 - 6b13 + b12 + 9b10 - b9 + 3b1) * q^85 + (5b8 - b7 + b4 + b3 - 4b2 - 1) * q^86 + (2b7 - b5 - b3 + b2 - 2) q^88 + (-2b15 + b14 - 2b13 + 4b12 + 2b11 - 2b10 - 2b1) * q^89 + (-b14 - 7b13 + 4b12 - 4b11 + 6b10 + b9 - 2b1) q^90 + (-b8 + 7b7 + 3b6 - 3b5 - 5b4 + b3 + 5b2 - 3) q^91 + (-b8 + b7 + b4 - b3 - 2) * q^92 + (b8 - 6b7 + b6 + 4b5 - 2b4 + 2b3 - 2b2 + 2) q^93 + (3b8 - 4b7 - b6 + 2b4 - b3 - 3b2 - 1) * q^94 + (b15 + 2b14 - 7b13 + 3b12 - 2b11 + 8b10 + 2b9) * q^95 + b6 * q^96 + (-2b15 - 5b13 - b12 - b11 + 6b10 + 4b9 + b1) * q^97 + (-b14 - 3b13 - 3b12 - 2b11 + 3b10 - b9 + b1) * q^98 + (-3b15 + 2b14 - 5b13 + 7b12 - b11 + 7b10 - 4b9 + b1) * q^99
