 Self dual: no Analytic conductor: $$3.11416567883$$ Analytic rank: $$0$$ Dimension: $$24$$ Relative dimension: $$12$$ over $$\Q(i)$$ Twist minimal: yes Sato-Tate group: $\mathrm{SU}(2)[C_{4}]$

## $q$-expansion

The algebraic $$q$$-expansion of this newform has not been computed, but we have computed the trace expansion.

 $$\operatorname{Tr}(f)(q) =$$ $$24 q + 4 q^{3} + 12 q^{9}+O(q^{10})$$ 24 * q + 4 * q^3 + 12 * q^9 $$\operatorname{Tr}(f)(q) =$$ $$24 q + 4 q^{3} + 12 q^{9} + 4 q^{10} - 8 q^{12} - 8 q^{13} + 16 q^{14} - 24 q^{16} - 52 q^{17} + 16 q^{22} + 16 q^{23} + 16 q^{25} - 56 q^{27} + 80 q^{29} + 8 q^{30} - 20 q^{35} + 16 q^{38} + 32 q^{39} - 48 q^{42} + 28 q^{43} - 4 q^{48} - 20 q^{51} - 8 q^{52} - 72 q^{53} + 24 q^{55} - 64 q^{61} + 32 q^{62} + 12 q^{65} + 8 q^{66} - 52 q^{68} + 16 q^{69} + 120 q^{74} + 24 q^{75} - 32 q^{77} - 64 q^{78} + 12 q^{81} + 32 q^{82} - 16 q^{88} - 44 q^{90} + 64 q^{91} - 16 q^{92} - 96 q^{95}+O(q^{100})$$ 24 * q + 4 * q^3 + 12 * q^9 + 4 * q^10 - 8 * q^12 - 8 * q^13 + 16 * q^14 - 24 * q^16 - 52 * q^17 + 16 * q^22 + 16 * q^23 + 16 * q^25 - 56 * q^27 + 80 * q^29 + 8 * q^30 - 20 * q^35 + 16 * q^38 + 32 * q^39 - 48 * q^42 + 28 * q^43 - 4 * q^48 - 20 * q^51 - 8 * q^52 - 72 * q^53 + 24 * q^55 - 64 * q^61 + 32 * q^62 + 12 * q^65 + 8 * q^66 - 52 * q^68 + 16 * q^69 + 120 * q^74 + 24 * q^75 - 32 * q^77 - 64 * q^78 + 12 * q^81 + 32 * q^82 - 16 * q^88 - 44 * q^90 + 64 * q^91 - 16 * q^92 - 96 * q^95
