Newform orbit 595.2.a.i

Trace form

The 4 newforms in this orbit are conjugate over $\mathbb{Q}$ ; the sum of their $q$ -expansions is

$4q + q^{2} - 2q^{3} + 3q^{4} + 4q^{5} - 5q^{6} + 4q^{7} + 6q^{8} + 2q^{9} + q^{10} + 5q^{11} - 8q^{12} + 3q^{13} + q^{14} - 2q^{15} + 9q^{16} + 4q^{17} + 4q^{18} - 5q^{19} + 3q^{20} - 2q^{21} + 4q^{22} + 11q^{23} - q^{24} + O(q^{25})$

Coefficient field

The coefficients $a_n$ generate a number field of degree 4. It is generated by the eigenvalue $\alpha$ of $T = T_{2} + 3T_{3} + 5T_{11} + 7T_{13} + 9T_{19}$ , whose minimal polynomial is

$x^{4} + 4x^{3} - 545x^{2} + 5877x - 18281$

Atkin–Lehner signs

$p$	$w_p$
5	$-1$
7	$-1$
17	$-1$

For $p \parallel N$ every form in the orbit has $a_p = -p^{k/2-1} w_p$ . The Fricke sign is $w_N = -1$ , so the sign of the functional equation is $(-1)^{k/2} w_N = +1$ : each L-function in the orbit has even analytic rank.

$\operatorname{tr} a_n$ for every $n \le 1000$ is in the JSON.

Provenance

Stored in the atlas: computed by Sagebrush's modular symbols engine in 0.302 s (one thread) and proven: the dimensions are certified, and the characteristic polynomial of $T$ over $\mathbb{Z}$ is reconstructed by CRT past a rigorous coefficient bound. The label, dimension and $\operatorname{tr} a_p$ for every $p < 1000$ equal LMFDB's.
