 Level: $$N$$ $$=$$ $$1600 = 2^{6} \cdot 5^{2}$$ Weight: $$k$$ $$=$$ $$2$$ Character orbit: $$[\chi]$$ $$=$$ 1600.n (of order $$4$$, degree $$2$$, not minimal)

## Newform invariants

 Self dual: no Analytic conductor: $$12.7760643234$$ Analytic rank: $$0$$ Dimension: $$2$$ Coefficient field: $$\Q(\sqrt{-1})$$ Defining polynomial: $$x^{2} + 1$$ Coefficient ring: $$\Z[a_1, a_2, a_3]$$ Coefficient ring index: $$1$$ Twist minimal: no (minimal twist has level 100) Sato-Tate group: $\mathrm{U}(1)[D_{4}]$

## $q$-expansion

Coefficients of the $$q$$-expansion are expressed in terms of $$i = \sqrt{-1}$$. We also show the integral $$q$$-expansion of the trace form.

 $$f(q)$$ $$=$$ $$q + ( 1 + i ) q^{3} + ( 3 - 3 i ) q^{7} -i q^{9} +O(q^{10})$$ $$q + ( 1 + i ) q^{3} + ( 3 - 3 i ) q^{7} -i q^{9} + 6 q^{21} + ( -1 - i ) q^{23} + ( 4 - 4 i ) q^{27} -6 i q^{29} + 12 q^{41} + ( -9 - 9 i ) q^{43} + ( -7 + 7 i ) q^{47} -11 i q^{49} + 8 q^{61} + ( -3 - 3 i ) q^{63} + ( -3 + 3 i ) q^{67} -2 i q^{69} + 5 q^{81} + ( 11 + 11 i ) q^{83} + ( 6 - 6 i ) q^{87} + 6 i q^{89} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q + 2q^{3} + 6q^{7} + O(q^{10})$$ $$2q + 2q^{3} + 6q^{7} + 12q^{21} - 2q^{23} + 8q^{27} + 24q^{41} - 18q^{43} - 14q^{47} + 16q^{61} - 6q^{63} - 6q^{67} + 10q^{81} + 22q^{83} + 12q^{87} + O(q^{100})$$
