 Self dual: yes Analytic conductor: $$36.7950652514$$ Analytic rank: $$1$$ Dimension: $$2$$ Coefficient field: $$\Q(\sqrt{2})$$ Defining polynomial: $$x^{2} - 2$$ Coefficient ring: $$\Z[a_1, \ldots, a_{17}]$$ Coefficient ring index: $$1$$ Twist minimal: no (minimal twist has level 512) Fricke sign: $$1$$ Sato-Tate group: $N(\mathrm{U}(1))$

## $q$-expansion

Coefficients of the $$q$$-expansion are expressed in terms of $$\beta = \sqrt{2}$$. We also show the integral $$q$$-expansion of the trace form.

 $$f(q)$$ $$=$$ $$q +O(q^{10})$$ $$q + ( 2 - 3 \beta ) q^{11} + 4 \beta q^{17} + ( -6 + \beta ) q^{19} -5 q^{25} + 6 q^{41} + ( -6 + 5 \beta ) q^{43} -7 q^{49} + ( -10 + 3 \beta ) q^{59} + ( -6 - 7 \beta ) q^{67} -12 \beta q^{73} + ( 2 + 9 \beta ) q^{83} -4 \beta q^{89} + 12 \beta q^{97} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2 q + O(q^{10})$$ $$2 q + 4 q^{11} - 12 q^{19} - 10 q^{25} + 12 q^{41} - 12 q^{43} - 14 q^{49} - 20 q^{59} - 12 q^{67} + 4 q^{83} + O(q^{100})$$
