The $q$ -expansion and trace form are shown below.

$f(q)$	$=$	$q + ( - i - 1) q^{2} + i q^{4} + (i + 1) q^{7} + i q^{9} + (i - 1) q^{13} - 2 i q^{14} + q^{16} + ( - i - 1) q^{17} + ( - i + 1) q^{18} + 2 q^{26} + (i - 1) q^{28} + ( - i - 1) q^{32} + 2 i q^{34} - q^{36} + \cdots + ( - i + 1) q^{98} +O(q^{100})$ q + (-z - 1) * q^2 + z * q^4 + (z + 1) * q^7 + z * q^9 + (z - 1) * q^13 - 2z q^14 + q^16 + (-z - 1) * q^17 + (-z + 1) * q^18 + 2 * q^26 + (z - 1) * q^28 + (-z - 1) * q^32 + 2z q^34 - q^36 + (z - 1) * q^43 + z * q^49 + (-z - 1) * q^52 + 2z q^59 + (z - 1) * q^63 + z * q^64 + (-z + 1) * q^68 - 2 * q^71 + (z - 1) * q^73 - q^81 + (-z + 1) * q^83 + 2 * q^86 - 2 * q^91 + (-z + 1) * q^98
$\operatorname{Tr}(f)(q)$	$=$	$2 q - 2 q^{2} + 2 q^{7} - 2 q^{13} + 2 q^{16} - 2 q^{17} + 2 q^{18} + 4 q^{26} - 2 q^{28} - 2 q^{32} - 2 q^{36} - 2 q^{43} - 2 q^{52} - 2 q^{63} + 2 q^{68} - 4 q^{71} - 2 q^{73} - 2 q^{81} + 2 q^{83} + 4 q^{86}+ \cdots + 2 q^{98}+O(q^{100})$ 2 * q - 2 * q^2 + 2 * q^7 - 2 * q^13 + 2 * q^16 - 2 * q^17 + 2 * q^18 + 4 * q^26 - 2 * q^28 - 2 * q^32 - 2 * q^36 - 2 * q^43 - 2 * q^52 - 2 * q^63 + 2 * q^68 - 4 * q^71 - 2 * q^73 - 2 * q^81 + 2 * q^83 + 4 * q^86 - 4 * q^91 + 2 * q^98

Character values

We give the values of $\chi$ on generators for $\left(\mathbb{Z}/3025\mathbb{Z}\right)^\times$ .

$n$	$727$	$2301$
$\chi(n)$	$i$	$1$

Embeddings

For each embedding $\iota_m$ of the coefficient field, the values $\iota_m(a_n)$ are shown below.
