Newform orbit 96.6.a.b

$q$ -expansion

$q - 9q^{3} - 14q^{5} + 100q^{7} + 81q^{9} + 220q^{11} - 818q^{13} + 126q^{15} - 774q^{17} - 1436q^{19} - 900q^{21} + 192q^{23} + O(q^{25})$

Coefficient field

The coefficients $a_n$ generate $\mathbb{Q}$ . The eigenvalue of $T = T_{5} + 3T_{7} + 5T_{13} + 7T_{17} + 9T_{19}$ is a root of

$x + 22146$

Atkin–Lehner signs

$p$	$w_p$
2	— ( $2^2 \mid 96$ )

Provenance

Stored in the atlas: computed by Sagebrush's modular symbols engine in 0.491 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

T = [(5, 1), (7, 3), (13, 5), (17, 7), (19, 9)]; h of degree 10 = 1 x 10 (phi(ord eps) x dim S_k^new); 6 primes, 0 rejected
