## Newspace parameters

 Level: $$N$$ $$=$$ $$1728 = 2^{6} \cdot 3^{3}$$ Weight: $$k$$ $$=$$ $$3$$ Character orbit: $$[\chi]$$ $$=$$ 1728.g (of order $$2$$, degree $$1$$, not minimal)

## Newform invariants

 Self dual: no Analytic conductor: $$47.0845896815$$ Analytic rank: $$0$$ Dimension: $$2$$ Coefficient field: $$\Q(\sqrt{-3})$$ Coefficient ring: $$\Z[a_1, \ldots, a_{19}]$$ Coefficient ring index: $$2$$ Twist minimal: no (minimal twist has level 108) Sato-Tate group: $\mathrm{SU}(2)[C_{2}]$

## $q$-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.

 $$f(q)$$ $$=$$ $$q -7 q^{5} + ( 5 - 10 \zeta_{6} ) q^{7} +O(q^{10})$$ $$q -7 q^{5} + ( 5 - 10 \zeta_{6} ) q^{7} + ( 5 - 10 \zeta_{6} ) q^{11} -20 q^{13} -8 q^{17} + ( 6 - 12 \zeta_{6} ) q^{19} + ( 2 - 4 \zeta_{6} ) q^{23} + 24 q^{25} -10 q^{29} + ( 31 - 62 \zeta_{6} ) q^{31} + ( -35 + 70 \zeta_{6} ) q^{35} + 10 q^{37} -50 q^{41} + ( 10 - 20 \zeta_{6} ) q^{43} + ( -50 + 100 \zeta_{6} ) q^{47} -26 q^{49} + 47 q^{53} + ( -35 + 70 \zeta_{6} ) q^{55} + ( -20 + 40 \zeta_{6} ) q^{59} + 64 q^{61} + 140 q^{65} + ( 50 - 100 \zeta_{6} ) q^{67} -55 q^{73} -75 q^{77} + ( -4 + 8 \zeta_{6} ) q^{79} + ( 17 - 34 \zeta_{6} ) q^{83} + 56 q^{85} + 10 q^{89} + ( -100 + 200 \zeta_{6} ) q^{91} + ( -42 + 84 \zeta_{6} ) q^{95} -25 q^{97} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q - 14q^{5} + O(q^{10})$$ $$2q - 14q^{5} - 40q^{13} - 16q^{17} + 48q^{25} - 20q^{29} + 20q^{37} - 100q^{41} - 52q^{49} + 94q^{53} + 128q^{61} + 280q^{65} - 110q^{73} - 150q^{77} + 112q^{85} + 20q^{89} - 50q^{97} + O(q^{100})$$
