## Newspace parameters

 Level: $$N$$ $$=$$ $$2880 = 2^{6} \cdot 3^{2} \cdot 5$$ Weight: $$k$$ $$=$$ $$2$$ Character orbit: $$[\chi]$$ $$=$$ 2880.o (of order $$2$$, degree $$1$$, not minimal)

## Newform invariants

 Self dual: no Analytic conductor: $$22.9969157821$$ Analytic rank: $$0$$ Dimension: $$4$$ Coefficient field: $$\Q(\zeta_{8})$$ Defining polynomial: $$x^{4} + 1$$ Coefficient ring: $$\Z[a_1, \ldots, a_{17}]$$ Coefficient ring index: $$3^{2}$$ Twist minimal: no (minimal twist has level 720) Sato-Tate group: $\mathrm{U}(1)[D_{2}]$

## $q$-expansion

Coefficients of the $$q$$-expansion are expressed in terms of a primitive root of unity $$\zeta_{8}$$. We also show the integral $$q$$-expansion of the trace form.

 $$f(q)$$ $$=$$ $$q + ( -2 \zeta_{8} + \zeta_{8}^{3} ) q^{5} +O(q^{10})$$ $$q + ( -2 \zeta_{8} + \zeta_{8}^{3} ) q^{5} -6 \zeta_{8}^{2} q^{13} + ( 3 \zeta_{8} - 3 \zeta_{8}^{3} ) q^{17} + ( 4 + 3 \zeta_{8}^{2} ) q^{25} + ( 7 \zeta_{8} + 7 \zeta_{8}^{3} ) q^{29} -12 \zeta_{8}^{2} q^{37} + ( \zeta_{8} + \zeta_{8}^{3} ) q^{41} -7 q^{49} + ( -9 \zeta_{8} + 9 \zeta_{8}^{3} ) q^{53} -10 q^{61} + ( 6 \zeta_{8} + 12 \zeta_{8}^{3} ) q^{65} -6 \zeta_{8}^{2} q^{73} + ( -9 - 3 \zeta_{8}^{2} ) q^{85} + ( -13 \zeta_{8} - 13 \zeta_{8}^{3} ) q^{89} -18 \zeta_{8}^{2} q^{97} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$4q + O(q^{10})$$ $$4q + 16q^{25} - 28q^{49} - 40q^{61} - 36q^{85} + O(q^{100})$$

## Character values

We give the values of $$\chi$$ on generators for $$\left(\mathbb{Z}/2880\mathbb{Z}\right)^\times$$.
