Newform orbit 110.4.a.c

$q$ -expansion

$q - 2q^{2} + 4q^{3} + 4q^{4} + 5q^{5} - 8q^{6} + 20q^{7} - 8q^{8} - 11q^{9} - 10q^{10} + 11q^{11} + 16q^{12} + 26q^{13} - 40q^{14} + 20q^{15} + 16q^{16} - 42q^{17} + 22q^{18} + 116q^{19} + 20q^{20} + 80q^{21} - 22q^{22} + 96q^{23} - 32q^{24} + O(q^{25})$

Coefficient field

The coefficients $a_n$ generate $\mathbb{Q}$ . The eigenvalue of $T = T_{3} + 3T_{7} + 5T_{13} + 7T_{17}$ is a root of

$x + 100$

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 even analytic rank.

Provenance

Stored in the atlas: computed by Sagebrush's modular symbols engine in 0.154 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, 7, 4, 11, 20, 58] (certified at ell = 2147482921)
T = [(3, 1), (7, 3), (13, 5), (17, 7)]; h of degree 10 = 1 x 10 (phi(ord eps) x dim S_k^new); 4 primes, 0 rejected
