Newform orbit 583.2.a.g

Trace form

The 8 newforms in this orbit are conjugate over $\mathbb{Q}$ ; the sum of their $q$ -expansions is

$8q - 2q^{2} - 8q^{3} + 6q^{4} - 11q^{5} + 2q^{6} - q^{7} - 12q^{8} + 6q^{9} + 10q^{10} + 8q^{11} - 6q^{12} - 3q^{13} - 14q^{14} + 10q^{15} + 10q^{16} - 19q^{17} - 6q^{18} - 5q^{19} - 33q^{20} - 10q^{21} - 2q^{22} - 13q^{23} + 12q^{24} + O(q^{25})$

Coefficient field

The coefficients $a_n$ generate a number field of degree 8. It is generated by the eigenvalue $\alpha$ of $T = T_{2} + 3T_{3}$ , whose minimal polynomial is

$x^{8} + 26x^{7} + 186x^{6} - 176x^{5} - 5567x^{4} - 9738x^{3} + 25796x^{2} + 41512x - 12944$

Atkin–Lehner signs

$p$	$w_p$
11	$-1$
53	$-1$

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 odd 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 0.221 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.

The engine's checks
