## $q$-expansion

gp: mfcoefs(f, 20)

Coefficients of the $$q$$-expansion are expressed in terms of $$\beta = \sqrt{6}$$. We also show the integral $$q$$-expansion of the trace form.

 $$f(q)$$ $$=$$ $$q + q^{5} + (\beta + 1) q^{7}+O(q^{10})$$ q + q^5 + (b + 1) * q^7 $$q + q^{5} + (\beta + 1) q^{7} + 2 q^{17} + ( - 2 \beta - 2) q^{19} + (\beta + 5) q^{23} + q^{25} + (2 \beta - 3) q^{29} + ( - 2 \beta + 6) q^{31} + (\beta + 1) q^{35} - 6 q^{37} + (2 \beta + 5) q^{41} + (4 \beta + 2) q^{43} + (\beta + 7) q^{47} + 2 \beta q^{49} + ( - 4 \beta + 2) q^{53} + ( - 2 \beta + 6) q^{59} - 3 q^{61} + ( - 5 \beta - 1) q^{67} - 4 \beta q^{71} + (4 \beta + 4) q^{73} + ( - 2 \beta - 2) q^{79} + (\beta + 3) q^{83} + 2 q^{85} + ( - 4 \beta + 7) q^{89} + ( - 2 \beta - 2) q^{95} + 2 q^{97} +O(q^{100})$$ q + q^5 + (b + 1) * q^7 + 2 * q^17 + (-2*b - 2) * q^19 + (b + 5) * q^23 + q^25 + (2*b - 3) * q^29 + (-2*b + 6) * q^31 + (b + 1) * q^35 - 6 * q^37 + (2*b + 5) * q^41 + (4*b + 2) * q^43 + (b + 7) * q^47 + 2*b * q^49 + (-4*b + 2) * q^53 + (-2*b + 6) * q^59 - 3 * q^61 + (-5*b - 1) * q^67 - 4*b * q^71 + (4*b + 4) * q^73 + (-2*b - 2) * q^79 + (b + 3) * q^83 + 2 * q^85 + (-4*b + 7) * q^89 + (-2*b - 2) * q^95 + 2 * q^97 $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2 q + 2 q^{5} + 2 q^{7}+O(q^{10})$$ 2 * q + 2 * q^5 + 2 * q^7 $$2 q + 2 q^{5} + 2 q^{7} + 4 q^{17} - 4 q^{19} + 10 q^{23} + 2 q^{25} - 6 q^{29} + 12 q^{31} + 2 q^{35} - 12 q^{37} + 10 q^{41} + 4 q^{43} + 14 q^{47} + 4 q^{53} + 12 q^{59} - 6 q^{61} - 2 q^{67} + 8 q^{73} - 4 q^{79} + 6 q^{83} + 4 q^{85} + 14 q^{89} - 4 q^{95} + 4 q^{97}+O(q^{100})$$ 2 * q + 2 * q^5 + 2 * q^7 + 4 * q^17 - 4 * q^19 + 10 * q^23 + 2 * q^25 - 6 * q^29 + 12 * q^31 + 2 * q^35 - 12 * q^37 + 10 * q^41 + 4 * q^43 + 14 * q^47 + 4 * q^53 + 12 * q^59 - 6 * q^61 - 2 * q^67 + 8 * q^73 - 4 * q^79 + 6 * q^83 + 4 * q^85 + 14 * q^89 - 4 * q^95 + 4 * q^97
