## Newspace parameters

 Level: $$N$$ $$=$$ $$7056 = 2^{4} \cdot 3^{2} \cdot 7^{2}$$ Weight: $$k$$ $$=$$ $$2$$ Character orbit: $$[\chi]$$ $$=$$ 7056.a (trivial)

## Newform invariants

 Self dual: yes Analytic conductor: $$56.3424436662$$ Analytic rank: $$1$$ Dimension: $$2$$ Coefficient field: $$\Q(\sqrt{2})$$ Defining polynomial: $$x^{2} - 2$$ Coefficient ring: $$\Z[a_1, \ldots, a_{5}]$$ Coefficient ring index: $$1$$ Twist minimal: no (minimal twist has level 3528) Fricke sign: $$1$$ Sato-Tate group: $\mathrm{SU}(2)$

## $q$-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.

 $$f(q)$$ $$=$$ $$q + \beta q^{5} +O(q^{10})$$ $$q + \beta q^{5} + \beta q^{13} -\beta q^{17} -4 q^{23} -3 q^{25} + 6 q^{29} -4 \beta q^{31} -4 q^{37} -5 \beta q^{41} -4 q^{43} -8 \beta q^{47} + 4 q^{53} + 4 \beta q^{59} + 3 \beta q^{61} + 2 q^{65} -4 q^{67} -12 q^{71} -5 \beta q^{73} -8 q^{79} + 4 \beta q^{83} -2 q^{85} + 9 \beta q^{89} + 3 \beta q^{97} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q + O(q^{10})$$ $$2q - 8q^{23} - 6q^{25} + 12q^{29} - 8q^{37} - 8q^{43} + 8q^{53} + 4q^{65} - 8q^{67} - 24q^{71} - 16q^{79} - 4q^{85} + O(q^{100})$$
