## $q$-expansion

gp: mfcoefs(f, 20)

Coefficients of the $$q$$-expansion are expressed in terms of $$\beta = \frac{1}{2}(1 + \sqrt{13})$$. We also show the integral $$q$$-expansion of the trace form.

 $$f(q)$$ $$=$$ $$q + \beta q^{5} + q^{7}+O(q^{10})$$ q + b * q^5 + q^7 $$q + \beta q^{5} + q^{7} + (2 \beta + 2) q^{13} - q^{17} + (2 \beta + 2) q^{19} + (\beta - 2) q^{25} + (\beta + 2) q^{31} + \beta q^{35} + ( - 2 \beta + 2) q^{37} + ( - 3 \beta + 3) q^{41} + (\beta + 5) q^{43} - 2 \beta q^{47} + q^{49} + ( - \beta + 6) q^{53} - 4 \beta q^{59} + ( - 3 \beta - 1) q^{61} + (4 \beta + 6) q^{65} + (\beta - 4) q^{67} + (6 \beta - 6) q^{71} + ( - 3 \beta - 1) q^{73} + (2 \beta + 8) q^{79} - 6 q^{83} - \beta q^{85} + (2 \beta + 12) q^{89} + (2 \beta + 2) q^{91} + (4 \beta + 6) q^{95} + ( - \beta - 4) q^{97} +O(q^{100})$$ q + b * q^5 + q^7 + (2*b + 2) * q^13 - q^17 + (2*b + 2) * q^19 + (b - 2) * q^25 + (b + 2) * q^31 + b * q^35 + (-2*b + 2) * q^37 + (-3*b + 3) * q^41 + (b + 5) * q^43 - 2*b * q^47 + q^49 + (-b + 6) * q^53 - 4*b * q^59 + (-3*b - 1) * q^61 + (4*b + 6) * q^65 + (b - 4) * q^67 + (6*b - 6) * q^71 + (-3*b - 1) * q^73 + (2*b + 8) * q^79 - 6 * q^83 - b * q^85 + (2*b + 12) * q^89 + (2*b + 2) * q^91 + (4*b + 6) * q^95 + (-b - 4) * q^97 $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2 q + q^{5} + 2 q^{7}+O(q^{10})$$ 2 * q + q^5 + 2 * q^7 $$2 q + q^{5} + 2 q^{7} + 6 q^{13} - 2 q^{17} + 6 q^{19} - 3 q^{25} + 5 q^{31} + q^{35} + 2 q^{37} + 3 q^{41} + 11 q^{43} - 2 q^{47} + 2 q^{49} + 11 q^{53} - 4 q^{59} - 5 q^{61} + 16 q^{65} - 7 q^{67} - 6 q^{71} - 5 q^{73} + 18 q^{79} - 12 q^{83} - q^{85} + 26 q^{89} + 6 q^{91} + 16 q^{95} - 9 q^{97}+O(q^{100})$$ 2 * q + q^5 + 2 * q^7 + 6 * q^13 - 2 * q^17 + 6 * q^19 - 3 * q^25 + 5 * q^31 + q^35 + 2 * q^37 + 3 * q^41 + 11 * q^43 - 2 * q^47 + 2 * q^49 + 11 * q^53 - 4 * q^59 - 5 * q^61 + 16 * q^65 - 7 * q^67 - 6 * q^71 - 5 * q^73 + 18 * q^79 - 12 * q^83 - q^85 + 26 * q^89 + 6 * q^91 + 16 * q^95 - 9 * q^97
