## 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: $$\Z[a_1, \ldots, a_{37}]$$ 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.

 $$f(q)$$ $$=$$ $$q + 3 i q^{7} +O(q^{10})$$ $$q + 3 i q^{7} -2 q^{11} + 3 i q^{13} -6 i q^{17} + 7 q^{19} + 6 i q^{23} -2 q^{29} -5 q^{31} + 10 i q^{37} -12 q^{41} -3 i q^{43} + 10 i q^{47} -2 q^{49} -6 q^{59} -13 q^{61} + 7 i q^{67} + 4 q^{71} + 6 i q^{73} -6 i q^{77} + 8 q^{79} -6 i q^{83} + 16 q^{89} -9 q^{91} -7 i q^{97} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q + O(q^{10})$$ $$2q - 4q^{11} + 14q^{19} - 4q^{29} - 10q^{31} - 24q^{41} - 4q^{49} - 12q^{59} - 26q^{61} + 8q^{71} + 16q^{79} + 32q^{89} - 18q^{91} + O(q^{100})$$

## Character values

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