## Newspace parameters

 Level: $$N$$ $$=$$ $$1368 = 2^{3} \cdot 3^{2} \cdot 19$$ Weight: $$k$$ $$=$$ $$2$$ Character orbit: $$[\chi]$$ $$=$$ 1368.s (of order $$3$$, degree $$2$$, minimal)

## Newform invariants

 Self dual: no Analytic conductor: $$10.9235349965$$ Analytic rank: $$0$$ Dimension: $$2$$ Coefficient field: $$\Q(\sqrt{-3})$$ Defining polynomial: $$x^{2} - x + 1$$ Coefficient ring: $$\Z[a_1, \ldots, a_{13}]$$ Coefficient ring index: $$1$$ Twist minimal: no (minimal twist has level 152) 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.

 $$f(q)$$ $$=$$ $$q + ( 3 - 3 \zeta_{6} ) q^{5} +O(q^{10})$$ $$q + ( 3 - 3 \zeta_{6} ) q^{5} + 4 q^{11} + 5 \zeta_{6} q^{13} + ( -5 + 5 \zeta_{6} ) q^{17} + ( 5 - 2 \zeta_{6} ) q^{19} -\zeta_{6} q^{23} -4 \zeta_{6} q^{25} + 3 \zeta_{6} q^{29} + 4 q^{31} + 2 q^{37} + ( -5 + 5 \zeta_{6} ) q^{41} + ( 11 - 11 \zeta_{6} ) q^{43} -5 \zeta_{6} q^{47} -7 q^{49} -9 \zeta_{6} q^{53} + ( 12 - 12 \zeta_{6} ) q^{55} + ( 13 - 13 \zeta_{6} ) q^{59} + \zeta_{6} q^{61} + 15 q^{65} + 5 \zeta_{6} q^{67} + ( 1 - \zeta_{6} ) q^{71} + ( 9 - 9 \zeta_{6} ) q^{73} + ( -17 + 17 \zeta_{6} ) q^{79} -16 q^{83} + 15 \zeta_{6} q^{85} + 3 \zeta_{6} q^{89} + ( 9 - 15 \zeta_{6} ) q^{95} + ( 13 - 13 \zeta_{6} ) q^{97} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q + 3q^{5} + O(q^{10})$$ $$2q + 3q^{5} + 8q^{11} + 5q^{13} - 5q^{17} + 8q^{19} - q^{23} - 4q^{25} + 3q^{29} + 8q^{31} + 4q^{37} - 5q^{41} + 11q^{43} - 5q^{47} - 14q^{49} - 9q^{53} + 12q^{55} + 13q^{59} + q^{61} + 30q^{65} + 5q^{67} + q^{71} + 9q^{73} - 17q^{79} - 32q^{83} + 15q^{85} + 3q^{89} + 3q^{95} + 13q^{97} + O(q^{100})$$
