Newform orbit 114.4.a.c

$q$ -expansion

$q - 2q^{2} + 3q^{3} + 4q^{4} + 12q^{5} - 6q^{6} + 4q^{7} - 8q^{8} + 9q^{9} - 24q^{10} + 8q^{11} + 12q^{12} - 24q^{13} - 8q^{14} + 36q^{15} + 16q^{16} + 62q^{17} - 18q^{18} + 19q^{19} + 48q^{20} + 12q^{21} - 16q^{22} + 194q^{23} - 24q^{24} + O(q^{25})$

Coefficient field

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

$x - 24$

Atkin–Lehner signs

$p$	$w_p$
2	$+1$
3	$-1$
19	$-1$

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 0.127 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, 3, 6, 19, 38, 57, 114]: [1, 2, 2, 5, 6, 17, 22, 64] (certified at ell = 2147483647)
T = [(5, 1), (7, 3)]; h of degree 8 = 1 x 8 (phi(ord eps) x dim S_k^new); 2 primes, 0 rejected
