Newform orbit 110.6.a.b

$q$ -expansion

$q - 4q^{2} + 12q^{3} + 16q^{4} - 25q^{5} - 48q^{6} + 54q^{7} - 64q^{8} - 99q^{9} + 100q^{10} - 121q^{11} + 192q^{12} - 540q^{13} - 216q^{14} - 300q^{15} + 256q^{16} + 340q^{17} + 396q^{18} - 952q^{19} - 400q^{20} + 648q^{21} + 484q^{22} + 1092q^{23} - 768q^{24} + O(q^{25})$

Coefficient field

The coefficients $a_n$ generate $\mathbb{Q}$ . The eigenvalue of $T = T_{3} + T_{7}$ is a root of

$x - 66$

Atkin–Lehner signs

$p$	$w_p$
2	$+1$
5	$+1$
11	$+1$

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.

Provenance

Stored in the atlas: computed by Sagebrush's modular symbols engine in 0.324 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 engine's checks

dim M^+ at levels [1, 2, 5, 10, 11, 22, 55, 110]: [1, 2, 3, 9, 6, 17, 32, 94] (certified at ell = 2147482921)
T = [(3, 1), (7, 1)]; h of degree 14 = 1 x 14 (phi(ord eps) x dim S_k^new); 4 primes, 0 rejected
