## Newspace parameters

 Level: $$N$$ $$=$$ $$9900 = 2^{2} \cdot 3^{2} \cdot 5^{2} \cdot 11$$ Weight: $$k$$ $$=$$ $$2$$ Character orbit: $$[\chi]$$ $$=$$ 9900.c (of order $$2$$, degree $$1$$, not minimal)

## Newform invariants

 Self dual: no Analytic conductor: $$79.0518980011$$ Analytic rank: $$0$$ Dimension: $$2$$ Coefficient field: $$\Q(\sqrt{-1})$$ Defining polynomial: $$x^{2} + 1$$ Coefficient ring: $$\Z[a_1, \ldots, a_{7}]$$ Coefficient ring index: $$2$$ Twist minimal: no (minimal twist has level 660) Sato-Tate group: $\mathrm{SU}(2)[C_{2}]$

## $q$-expansion

Coefficients of the $$q$$-expansion are expressed in terms of $$i = \sqrt{-1}$$. We also show the integral $$q$$-expansion of the trace form.

 $$f(q)$$ $$=$$ $$q + 2 i q^{7} +O(q^{10})$$ $$q + 2 i q^{7} - q^{11} -2 i q^{13} -2 q^{19} + 8 q^{31} + 2 i q^{37} -2 i q^{43} + 3 q^{49} + 6 i q^{53} -12 q^{59} + 2 q^{61} -4 i q^{67} -2 i q^{73} -2 i q^{77} + 10 q^{79} -12 i q^{83} -6 q^{89} + 4 q^{91} + 14 i q^{97} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q + O(q^{10})$$ $$2q - 2q^{11} - 4q^{19} + 16q^{31} + 6q^{49} - 24q^{59} + 4q^{61} + 20q^{79} - 12q^{89} + 8q^{91} + O(q^{100})$$
