 Self dual: yes Analytic conductor: $$73.5901305028$$ Analytic rank: $$0$$ Dimension: $$2$$ Coefficient field: $$\Q(\sqrt{2})$$ Defining polynomial: $$x^{2} - 2$$ Coefficient ring: $$\Z[a_1, \ldots, a_{13}]$$ Coefficient ring index: $$1$$ Twist minimal: no (minimal twist has level 4608) 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.

 $$f(q)$$ $$=$$ $$q + 3 \beta q^{5} +O(q^{10})$$ $$q + 3 \beta q^{5} + 5 \beta q^{13} + 2 q^{17} + 13 q^{25} + 7 \beta q^{29} + 7 \beta q^{37} -10 q^{41} -7 q^{49} + 5 \beta q^{53} -11 \beta q^{61} + 30 q^{65} -6 q^{73} + 6 \beta q^{85} -16 q^{89} + 8 q^{97} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q + O(q^{10})$$ $$2q + 4q^{17} + 26q^{25} - 20q^{41} - 14q^{49} + 60q^{65} - 12q^{73} - 32q^{89} + 16q^{97} + O(q^{100})$$
