Newform orbit 573.2.a.f

Trace form

The 7 newforms in this orbit are conjugate over $\mathbb{Q}$ ; the sum of their $q$ -expansions is

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

Coefficient field

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

$x^{7} - 2x^{6} - 23x^{5} + 57x^{4} + 26x^{3} - 30x^{2} + 2x + 1$

Atkin–Lehner signs

$p$	$w_p$
3	$-1$
191	$+1$

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 0.216 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.
