 Level: $$N$$ = $$804 = 2^{2} \cdot 3 \cdot 67$$ Weight: $$k$$ = $$2$$ Character orbit: $$[\chi]$$ = 804.g (of order $$2$$ and degree $$1$$)

## Newform invariants

 Self dual: No Analytic conductor: $$6.41997232251$$ Analytic rank: $$0$$ Dimension: $$2$$ Coefficient field: $$\Q(\sqrt{-3})$$ Coefficient ring: $$\Z[a_1, a_2, a_3]$$ Coefficient ring index: $$2$$ Sato-Tate group: $\mathrm{U}(1)[D_{2}]$

## $q$-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.

 $$f(q)$$ $$=$$ $$q + ( -1 + 2 \zeta_{6} ) q^{3} + ( 2 - 4 \zeta_{6} ) q^{7} -3 q^{9} +O(q^{10})$$ $$q + ( -1 + 2 \zeta_{6} ) q^{3} + ( 2 - 4 \zeta_{6} ) q^{7} -3 q^{9} + ( 4 - 8 \zeta_{6} ) q^{13} -8 q^{19} + 6 q^{21} -5 q^{25} + ( 3 - 6 \zeta_{6} ) q^{27} + ( 6 - 12 \zeta_{6} ) q^{31} + 10 q^{37} + 12 q^{39} + ( -6 + 12 \zeta_{6} ) q^{43} -5 q^{49} + ( 8 - 16 \zeta_{6} ) q^{57} + ( 4 - 8 \zeta_{6} ) q^{61} + ( -6 + 12 \zeta_{6} ) q^{63} + ( 9 - 2 \zeta_{6} ) q^{67} + 10 q^{73} + ( 5 - 10 \zeta_{6} ) q^{75} + ( -10 + 20 \zeta_{6} ) q^{79} + 9 q^{81} -24 q^{91} + 18 q^{93} + ( 8 - 16 \zeta_{6} ) q^{97} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q - 6q^{9} + O(q^{10})$$ $$2q - 6q^{9} - 16q^{19} + 12q^{21} - 10q^{25} + 20q^{37} + 24q^{39} - 10q^{49} + 16q^{67} + 20q^{73} + 18q^{81} - 48q^{91} + 36q^{93} + O(q^{100})$$
