Newform orbit 96.6.a.d

$q$ -expansion

$q + 9q^{3} - 86q^{5} + 180q^{7} + 81q^{9} - 684q^{11} + 222q^{13} - 774q^{15} - 1942q^{17} - 1908q^{19} + 1620q^{21} - 144q^{23} + O(q^{25})$

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

$x + 29202$

Atkin–Lehner signs

$p$	$w_p$
2	— ( $2^2 \mid 96$ )
3	$-1$

For $p \parallel N$ every form in the orbit has $a_p = -p^{k/2-1} w_p$ .

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

dim M^+ at levels [1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96]: [1, 2, 3, 4, 7, 7, 13, 12, 24, 22, 44, 84] (certified at ell = 2147483497)
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
