## Newspace parameters

 Level: $$N$$ = $$864 = 2^{5} \cdot 3^{3}$$ Weight: $$k$$ = $$2$$ Character orbit: $$[\chi]$$ = 864.bf (of order $$18$$, degree $$6$$, not minimal)

## Newform invariants

 Self dual: no Analytic conductor: $$6.89907473464$$ Analytic rank: $$0$$ Dimension: $$204$$ Relative dimension: $$34$$ over $$\Q(\zeta_{18})$$ Coefficient ring index: multiple of None Twist minimal: no (minimal twist has level 216) Sato-Tate group: $\mathrm{SU}(2)[C_{18}]$

## $q$-expansion

The dimension is sufficiently large that we do not compute an algebraic $$q$$-expansion, but we have computed the trace expansion.

 $$\operatorname{Tr}(f)(q) =$$ $$204q + 12q^{7} - 12q^{9} + O(q^{10})$$ $$\operatorname{Tr}(f)(q) =$$ $$204q + 12q^{7} - 12q^{9} + 12q^{15} - 6q^{17} + 12q^{23} - 12q^{25} + 12q^{31} + 12q^{39} - 24q^{41} + 12q^{47} - 12q^{49} + 24q^{55} - 30q^{57} + 72q^{63} - 12q^{65} + 90q^{71} - 6q^{73} + 12q^{79} - 12q^{81} + 48q^{87} - 6q^{89} + 42q^{95} - 12q^{97} + O(q^{100})$$
