## 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 196) 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.

 $$f(q)$$ $$=$$ $$q + \beta q^{5} +O(q^{10})$$ $$q + \beta q^{5} + 4 q^{11} -3 \beta q^{13} + \beta q^{17} + 2 \beta q^{19} -4 q^{23} -3 q^{25} -8 q^{29} -8 q^{37} -5 \beta q^{41} + 4 q^{43} -4 \beta q^{47} -10 q^{53} + 4 \beta q^{55} -10 \beta q^{59} + 5 \beta q^{61} -6 q^{65} + 5 \beta q^{73} -8 q^{79} + 10 \beta q^{83} + 2 q^{85} + 5 \beta q^{89} + 4 q^{95} + \beta q^{97} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q + O(q^{10})$$ $$2q + 8q^{11} - 8q^{23} - 6q^{25} - 16q^{29} - 16q^{37} + 8q^{43} - 20q^{53} - 12q^{65} - 16q^{79} + 4q^{85} + 8q^{95} + O(q^{100})$$

## Embeddings
