Newform orbit 482.2.a.d

Trace form

The 6 newforms in this orbit are conjugate over $\mathbb{Q}$ ; the sum of their $q$ -expansions is

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

Coefficient field

The coefficients $a_n$ generate a number field of degree 6. It is generated by the eigenvalue $\alpha$ of $T = T_{3} + T_{5}$ , whose minimal polynomial is

$x^{6} + 3x^{5} - 34x^{4} - 65x^{3} + 222x^{2} + 451x + 97$

Atkin–Lehner signs

$p$	$w_p$
2	$+1$
241	$-1$

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 0.292 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

dim M^+ at levels [1, 2, 241, 482]: [0, 1, 20, 62] (certified at ell = 2147482801)
T = [(3, 1), (5, 1)]; h of degree 21 = 1 x 21 (phi(ord eps) x dim S_k^new); 3 primes, 0 rejected
