## $q$-expansion

sage: f.q_expansion() # note that sage often uses an isomorphic number field

gp: mfcoefs(f, 20)

Coefficients of the $$q$$-expansion are expressed in terms of $$\beta = 2i$$. We also show the integral $$q$$-expansion of the trace form.

 $$f(q)$$ $$=$$ $$q + \beta q^{5} - 3 q^{7}+O(q^{10})$$ q + b * q^5 - 3 * q^7 $$q + \beta q^{5} - 3 q^{7} - 3 q^{11} - 3 \beta q^{13} - \beta q^{17} - 3 \beta q^{19} + 2 \beta q^{23} + q^{25} + 2 \beta q^{29} - 3 \beta q^{35} + (3 \beta - 1) q^{37} + 3 q^{41} + 3 \beta q^{43} + 3 q^{47} + 2 q^{49} - 9 q^{53} - 3 \beta q^{55} - 2 \beta q^{59} + 12 q^{65} + 12 q^{67} - 3 q^{71} + 9 q^{73} + 9 q^{77} - 3 \beta q^{79} + 9 q^{83} + 4 q^{85} + 7 \beta q^{89} + 9 \beta q^{91} + 12 q^{95} + 6 \beta q^{97} +O(q^{100})$$ q + b * q^5 - 3 * q^7 - 3 * q^11 - 3*b * q^13 - b * q^17 - 3*b * q^19 + 2*b * q^23 + q^25 + 2*b * q^29 - 3*b * q^35 + (3*b - 1) * q^37 + 3 * q^41 + 3*b * q^43 + 3 * q^47 + 2 * q^49 - 9 * q^53 - 3*b * q^55 - 2*b * q^59 + 12 * q^65 + 12 * q^67 - 3 * q^71 + 9 * q^73 + 9 * q^77 - 3*b * q^79 + 9 * q^83 + 4 * q^85 + 7*b * q^89 + 9*b * q^91 + 12 * q^95 + 6*b * q^97 $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2 q - 6 q^{7}+O(q^{10})$$ 2 * q - 6 * q^7 $$2 q - 6 q^{7} - 6 q^{11} + 2 q^{25} - 2 q^{37} + 6 q^{41} + 6 q^{47} + 4 q^{49} - 18 q^{53} + 24 q^{65} + 24 q^{67} - 6 q^{71} + 18 q^{73} + 18 q^{77} + 18 q^{83} + 8 q^{85} + 24 q^{95}+O(q^{100})$$ 2 * q - 6 * q^7 - 6 * q^11 + 2 * q^25 - 2 * q^37 + 6 * q^41 + 6 * q^47 + 4 * q^49 - 18 * q^53 + 24 * q^65 + 24 * q^67 - 6 * q^71 + 18 * q^73 + 18 * q^77 + 18 * q^83 + 8 * q^85 + 24 * q^95
