## Newform invariants

 Self dual: no Analytic conductor: $$14.8684813214$$ 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: yes 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.

 $$f(q)$$ $$=$$ $$q + ( -1 + 19 \zeta_{6} ) q^{7} +O(q^{10})$$ $$q + ( -1 + 19 \zeta_{6} ) q^{7} -19 q^{13} + ( -107 + 107 \zeta_{6} ) q^{19} + 125 \zeta_{6} q^{25} + 289 \zeta_{6} q^{31} + ( -323 + 323 \zeta_{6} ) q^{37} + 71 q^{43} + ( -360 + 323 \zeta_{6} ) q^{49} + ( -182 + 182 \zeta_{6} ) q^{61} + 127 \zeta_{6} q^{67} + 271 \zeta_{6} q^{73} + ( 1387 - 1387 \zeta_{6} ) q^{79} + ( 19 - 361 \zeta_{6} ) q^{91} -1330 q^{97} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q + 17q^{7} + O(q^{10})$$ $$2q + 17q^{7} - 38q^{13} - 107q^{19} + 125q^{25} + 289q^{31} - 323q^{37} + 142q^{43} - 397q^{49} - 182q^{61} + 127q^{67} + 271q^{73} + 1387q^{79} - 323q^{91} - 2660q^{97} + O(q^{100})$$
