## Newspace parameters

 Level: $$N$$ $$=$$ $$1800 = 2^{3} \cdot 3^{2} \cdot 5^{2}$$ Weight: $$k$$ $$=$$ $$2$$ Character orbit: $$[\chi]$$ $$=$$ 1800.f (of order $$2$$, degree $$1$$, not minimal)

## Newform invariants

 Self dual: no Analytic conductor: $$14.3730723638$$ Analytic rank: $$0$$ Dimension: $$2$$ Coefficient field: $$\Q(\sqrt{-1})$$ Defining polynomial: $$x^{2} + 1$$ Coefficient ring: $$\Z[a_1, \ldots, a_{13}]$$ Coefficient ring index: $$1$$ Twist minimal: no (minimal twist has level 600) 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.

 $$f(q)$$ $$=$$ $$q + 5 i q^{7} +O(q^{10})$$ $$q + 5 i q^{7} + 6 q^{11} -3 i q^{13} -2 i q^{17} - q^{19} + 2 i q^{23} + 6 q^{29} + 3 q^{31} + 6 i q^{37} -4 q^{41} + 11 i q^{43} -10 i q^{47} -18 q^{49} + 8 i q^{53} -6 q^{59} + 3 q^{61} + i q^{67} + 12 q^{71} + 10 i q^{73} + 30 i q^{77} + 8 q^{79} + 6 i q^{83} -16 q^{89} + 15 q^{91} + 7 i q^{97} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q + O(q^{10})$$ $$2q + 12q^{11} - 2q^{19} + 12q^{29} + 6q^{31} - 8q^{41} - 36q^{49} - 12q^{59} + 6q^{61} + 24q^{71} + 16q^{79} - 32q^{89} + 30q^{91} + O(q^{100})$$

## Character values

We give the values of $$\chi$$ on generators for $$\left(\mathbb{Z}/1800\mathbb{Z}\right)^\times$$.
