$q$ -expansion

comment: 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 $i = \sqrt{-1}$ . We also show the integral $q$ -expansion of the trace form.

$f(q)$	$=$	$q - i q^{3} + 2 i q^{7} - q^{9} + q^{11} - 2 i q^{13} - 2 q^{19} + 2 q^{21} + i q^{27} + 8 q^{31} - i q^{33} + 2 i q^{37} - 2 q^{39} - 2 i q^{43} + 3 q^{49} - 6 i q^{53} + 2 i q^{57} + 12 q^{59} + 2 q^{61} + \cdots - q^{99} +O(q^{100})$ q - i * q^3 + 2i q^7 - q^9 + q^11 - 2i q^13 - 2 * q^19 + 2 * q^21 + i * q^27 + 8 * q^31 - i * q^33 + 2i q^37 - 2 * q^39 - 2i q^43 + 3 * q^49 - 6i q^53 + 2i q^57 + 12 * q^59 + 2 * q^61 - 2i q^63 - 4i q^67 - 2i q^73 + 2i q^77 + 10 * q^79 + q^81 + 12i q^83 + 6 * q^89 + 4 * q^91 - 8i q^93 + 14i q^97 - q^99
$\operatorname{Tr}(f)(q)$	$=$	$2 q - 2 q^{9} + 2 q^{11} - 4 q^{19} + 4 q^{21} + 16 q^{31} - 4 q^{39} + 6 q^{49} + 24 q^{59} + 4 q^{61} + 20 q^{79} + 2 q^{81} + 12 q^{89} + 8 q^{91} - 2 q^{99}+O(q^{100})$ 2 * q - 2 * q^9 + 2 * q^11 - 4 * q^19 + 4 * q^21 + 16 * q^31 - 4 * q^39 + 6 * q^49 + 24 * q^59 + 4 * q^61 + 20 * q^79 + 2 * q^81 + 12 * q^89 + 8 * q^91 - 2 * q^99

Character values
