## Newspace parameters

 Level: $$N$$ $$=$$ $$4000 = 2^{5} \cdot 5^{3}$$ Weight: $$k$$ $$=$$ $$1$$ Character orbit: $$[\chi]$$ $$=$$ 4000.e (of order $$2$$, degree $$1$$, not minimal)

## Newform invariants

 Self dual: yes Analytic conductor: $$1.99626005053$$ Analytic rank: $$0$$ Dimension: $$2$$ Coefficient field: $$\Q(\sqrt{5})$$ Defining polynomial: $$x^{2} - x - 1$$ Coefficient ring: $$\Z[a_1, \ldots, a_{7}]$$ Coefficient ring index: $$1$$ Twist minimal: no (minimal twist has level 1000) Projective image $$D_{5}$$ Projective field Galois closure of 5.1.1000000.1

## $q$-expansion

Coefficients of the $$q$$-expansion are expressed in terms of $$\beta = \frac{1}{2}(1 + \sqrt{5})$$. We also show the integral $$q$$-expansion of the trace form.

 $$f(q)$$ $$=$$ $$q + \beta q^{7} + q^{9} +O(q^{10})$$ $$q + \beta q^{7} + q^{9} + ( 1 - \beta ) q^{11} + ( -1 + \beta ) q^{13} + \beta q^{19} + ( 1 - \beta ) q^{23} -\beta q^{37} -\beta q^{41} + ( 1 - \beta ) q^{47} + \beta q^{49} -\beta q^{53} + \beta q^{59} + \beta q^{63} - q^{77} + q^{81} + ( -1 + \beta ) q^{89} + q^{91} + ( 1 - \beta ) q^{99} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q + q^{7} + 2q^{9} + O(q^{10})$$ $$2q + q^{7} + 2q^{9} + q^{11} - q^{13} + q^{19} + q^{23} - q^{37} - q^{41} + q^{47} + q^{49} - q^{53} + q^{59} + q^{63} - 2q^{77} + 2q^{81} - q^{89} + 2q^{91} + q^{99} + O(q^{100})$$

## Character values

We give the values of $$\chi$$ on generators for $$\left(\mathbb{Z}/4000\mathbb{Z}\right)^\times$$.
