 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: $$\Q(\sqrt{-3})$$ Defining polynomial: $$x^{2} - x + 1$$ Coefficient ring: $$\Z[a_1, \ldots, a_{25}]$$ Coefficient ring index: $$1$$ Twist minimal: no (minimal twist has level 36) 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.

 $$f(q)$$ $$=$$ $$q +O(q^{10})$$ $$q -2 q^{13} + 8 \zeta_{6} q^{19} + ( 5 - 5 \zeta_{6} ) q^{25} + ( -4 + 4 \zeta_{6} ) q^{31} + 10 \zeta_{6} q^{37} + 8 q^{43} + 14 \zeta_{6} q^{61} + ( 16 - 16 \zeta_{6} ) q^{67} + ( -10 + 10 \zeta_{6} ) q^{73} + 4 \zeta_{6} q^{79} -14 q^{97} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2 q + O(q^{10})$$ $$2 q - 4 q^{13} + 8 q^{19} + 5 q^{25} - 4 q^{31} + 10 q^{37} + 16 q^{43} + 14 q^{61} + 16 q^{67} - 10 q^{73} + 4 q^{79} - 28 q^{97} + O(q^{100})$$
