## Newspace parameters

 Level: $$N$$ $$=$$ $$2268 = 2^{2} \cdot 3^{4} \cdot 7$$ Weight: $$k$$ $$=$$ $$2$$ Character orbit: $$[\chi]$$ $$=$$ 2268.l (of order $$3$$, degree $$2$$, not minimal)

## Newform invariants

 Self dual: no Analytic conductor: $$18.1100711784$$ Analytic rank: $$0$$ Dimension: $$2$$ Coefficient field: $$\Q(\sqrt{-3})$$ Defining polynomial: $$x^{2} - x + 1$$ Coefficient ring: $$\Z[a_1, \ldots, a_{7}]$$ Coefficient ring index: $$1$$ Twist minimal: no (minimal twist has level 756) Sato-Tate group: $\mathrm{U}(1)[D_{3}]$

## $q$-expansion

Coefficients of the $$q$$-expansion are expressed in terms of a primitive root of unity $$\zeta_{6}$$. We also show the integral $$q$$-expansion of the trace form.

 $$f(q)$$ $$=$$ $$q + ( 2 + \zeta_{6} ) q^{7} +O(q^{10})$$ $$q + ( 2 + \zeta_{6} ) q^{7} + ( 7 - 7 \zeta_{6} ) q^{13} -8 \zeta_{6} q^{19} -5 q^{25} -11 \zeta_{6} q^{31} + \zeta_{6} q^{37} + 13 \zeta_{6} q^{43} + ( 3 + 5 \zeta_{6} ) q^{49} + ( 1 - \zeta_{6} ) q^{61} -11 \zeta_{6} q^{67} + ( 10 - 10 \zeta_{6} ) q^{73} + ( 13 - 13 \zeta_{6} ) q^{79} + ( 21 - 14 \zeta_{6} ) q^{91} + 19 \zeta_{6} q^{97} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q + 5q^{7} + O(q^{10})$$ $$2q + 5q^{7} + 7q^{13} - 8q^{19} - 10q^{25} - 11q^{31} + q^{37} + 13q^{43} + 11q^{49} + q^{61} - 11q^{67} + 10q^{73} + 13q^{79} + 28q^{91} + 19q^{97} + O(q^{100})$$

## Character values

We give the values of $$\chi$$ on generators for $$\left(\mathbb{Z}/2268\mathbb{Z}\right)^\times$$.
