## Newspace parameters

 Level: $$N$$ $$=$$ $$2736 = 2^{4} \cdot 3^{2} \cdot 19$$ Weight: $$k$$ $$=$$ $$2$$ Character orbit: $$[\chi]$$ $$=$$ 2736.s (of order $$3$$, degree $$2$$, not minimal)

## Newform invariants

 Self dual: no Analytic conductor: $$21.8470699930$$ Analytic rank: $$0$$ Dimension: $$2$$ Coefficient field: $$\Q(\sqrt{-3})$$ Defining polynomial: $$x^{2} - x + 1$$ Coefficient ring: $$\Z[a_1, \ldots, a_{19}]$$ Coefficient ring index: $$1$$ Twist minimal: no (minimal twist has level 38) 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.

 $$f(q)$$ $$=$$ $$q + 4 q^{7} +O(q^{10})$$ $$q + 4 q^{7} + 3 q^{11} -2 \zeta_{6} q^{13} + ( -6 + 6 \zeta_{6} ) q^{17} + ( 2 + 3 \zeta_{6} ) q^{19} + 6 \zeta_{6} q^{23} + 5 \zeta_{6} q^{25} -2 q^{31} -10 q^{37} + ( 9 - 9 \zeta_{6} ) q^{41} + ( -4 + 4 \zeta_{6} ) q^{43} + 9 q^{49} + 6 \zeta_{6} q^{53} + ( 9 - 9 \zeta_{6} ) q^{59} + 4 \zeta_{6} q^{61} -7 \zeta_{6} q^{67} + ( 6 - 6 \zeta_{6} ) q^{71} + ( 1 - \zeta_{6} ) q^{73} + 12 q^{77} + ( -4 + 4 \zeta_{6} ) q^{79} + 3 q^{83} + 6 \zeta_{6} q^{89} -8 \zeta_{6} q^{91} + ( -17 + 17 \zeta_{6} ) q^{97} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q + 8q^{7} + O(q^{10})$$ $$2q + 8q^{7} + 6q^{11} - 2q^{13} - 6q^{17} + 7q^{19} + 6q^{23} + 5q^{25} - 4q^{31} - 20q^{37} + 9q^{41} - 4q^{43} + 18q^{49} + 6q^{53} + 9q^{59} + 4q^{61} - 7q^{67} + 6q^{71} + q^{73} + 24q^{77} - 4q^{79} + 6q^{83} + 6q^{89} - 8q^{91} - 17q^{97} + O(q^{100})$$
