## Newspace parameters

 Level: $$N$$ $$=$$ $$1800 = 2^{3} \cdot 3^{2} \cdot 5^{2}$$ Weight: $$k$$ $$=$$ $$2$$ Character orbit: $$[\chi]$$ $$=$$ 1800.s (of order $$4$$, degree $$2$$, minimal)

## Newform invariants

 Self dual: no Analytic conductor: $$14.3730723638$$ Analytic rank: $$0$$ Dimension: $$4$$ Relative dimension: $$2$$ over $$\Q(i)$$ Coefficient field: $$\Q(\zeta_{8})$$ Defining polynomial: $$x^{4} + 1$$ Coefficient ring: $$\Z[a_1, \ldots, a_{29}]$$ Coefficient ring index: $$2$$ Twist minimal: no (minimal twist has level 360) Sato-Tate group: $\mathrm{SU}(2)[C_{4}]$

## $q$-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.

 $$f(q)$$ $$=$$ $$q +O(q^{10})$$ $$q + ( 4 \zeta_{8} + 4 \zeta_{8}^{3} ) q^{11} + ( -3 + 3 \zeta_{8}^{2} ) q^{13} -4 \zeta_{8}^{2} q^{19} -4 \zeta_{8} q^{23} + ( \zeta_{8} - \zeta_{8}^{3} ) q^{29} -8 q^{31} + ( -7 - 7 \zeta_{8}^{2} ) q^{37} + ( -\zeta_{8} - \zeta_{8}^{3} ) q^{41} + ( -4 + 4 \zeta_{8}^{2} ) q^{43} + 4 \zeta_{8}^{3} q^{47} -7 \zeta_{8}^{2} q^{49} + 12 \zeta_{8} q^{53} + ( -8 \zeta_{8} + 8 \zeta_{8}^{3} ) q^{59} -12 q^{61} + ( 8 + 8 \zeta_{8}^{2} ) q^{67} + ( 4 \zeta_{8} + 4 \zeta_{8}^{3} ) q^{71} + ( 3 - 3 \zeta_{8}^{2} ) q^{73} + 8 \zeta_{8}^{2} q^{79} + 16 \zeta_{8} q^{83} + ( -5 \zeta_{8} + 5 \zeta_{8}^{3} ) q^{89} + ( -5 - 5 \zeta_{8}^{2} ) q^{97} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$4q + O(q^{10})$$ $$4q - 12q^{13} - 32q^{31} - 28q^{37} - 16q^{43} - 48q^{61} + 32q^{67} + 12q^{73} - 20q^{97} + O(q^{100})$$
