## Newspace parameters

 Level: $$N$$ $$=$$ $$1764 = 2^{2} \cdot 3^{2} \cdot 7^{2}$$ Weight: $$k$$ $$=$$ $$2$$ Character orbit: $$[\chi]$$ $$=$$ 1764.k (of order $$3$$, degree $$2$$, not minimal)

## Newform invariants

 Self dual: no Analytic conductor: $$14.0856109166$$ Analytic rank: $$0$$ Dimension: $$2$$ Coefficient field: $$\Q(\sqrt{-3})$$ Coefficient ring: $$\Z[a_1, \ldots, a_{25}]$$ Coefficient ring index: $$1$$ Twist minimal: no (minimal twist has level 84) Sato-Tate group: $\mathrm{SU}(2)[C_{3}]$

## $q$-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.

 $$f(q)$$ $$=$$ $$q +O(q^{10})$$ $$q + ( -6 + 6 \zeta_{6} ) q^{11} -2 q^{13} -4 \zeta_{6} q^{19} -6 \zeta_{6} q^{23} + ( 5 - 5 \zeta_{6} ) q^{25} -6 q^{29} + ( 8 - 8 \zeta_{6} ) q^{31} -2 \zeta_{6} q^{37} + 12 q^{41} -4 q^{43} -12 \zeta_{6} q^{47} + ( -6 + 6 \zeta_{6} ) q^{53} -10 \zeta_{6} q^{61} + ( -8 + 8 \zeta_{6} ) q^{67} -6 q^{71} + ( -10 + 10 \zeta_{6} ) q^{73} + 4 \zeta_{6} q^{79} -12 q^{83} -12 \zeta_{6} q^{89} + 10 q^{97} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q + O(q^{10})$$ $$2q - 6q^{11} - 4q^{13} - 4q^{19} - 6q^{23} + 5q^{25} - 12q^{29} + 8q^{31} - 2q^{37} + 24q^{41} - 8q^{43} - 12q^{47} - 6q^{53} - 10q^{61} - 8q^{67} - 12q^{71} - 10q^{73} + 4q^{79} - 24q^{83} - 12q^{89} + 20q^{97} + O(q^{100})$$
