## Newspace parameters

 Level: $$N$$ = $$756 = 2^{2} \cdot 3^{3} \cdot 7$$ Weight: $$k$$ = $$2$$ Character orbit: $$[\chi]$$ = 756.t (of order $$6$$, degree $$2$$, minimal)

## Newform invariants

 Self dual: no Analytic conductor: $$6.03669039281$$ Analytic rank: $$0$$ Dimension: $$2$$ Coefficient field: $$\Q(\sqrt{-3})$$ Coefficient ring: $$\Z[a_1, \ldots, a_{25}]$$ Coefficient ring index: $$1$$ Twist minimal: yes Sato-Tate group: $\mathrm{U}(1)[D_{6}]$

## $q$-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.

 $$f(q)$$ $$=$$ $$q + ( 3 - 2 \zeta_{6} ) q^{7} +O(q^{10})$$ $$q + ( 3 - 2 \zeta_{6} ) q^{7} + ( 1 - 2 \zeta_{6} ) q^{13} + ( 4 - 2 \zeta_{6} ) q^{19} + ( 5 - 5 \zeta_{6} ) q^{25} + ( -1 - \zeta_{6} ) q^{31} -\zeta_{6} q^{37} + 13 q^{43} + ( 5 - 8 \zeta_{6} ) q^{49} + ( 18 - 9 \zeta_{6} ) q^{61} + ( -11 + 11 \zeta_{6} ) q^{67} + ( -8 - 8 \zeta_{6} ) q^{73} + 13 \zeta_{6} q^{79} + ( -1 - 4 \zeta_{6} ) q^{91} + ( 3 - 6 \zeta_{6} ) q^{97} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q + 4q^{7} + O(q^{10})$$ $$2q + 4q^{7} + 6q^{19} + 5q^{25} - 3q^{31} - q^{37} + 26q^{43} + 2q^{49} + 27q^{61} - 11q^{67} - 24q^{73} + 13q^{79} - 6q^{91} + O(q^{100})$$

## Character values

We give the values of $$\chi$$ on generators for $$\left(\mathbb{Z}/756\mathbb{Z}\right)^\times$$.
