Newform orbit 144.4.a.e

$q$ -expansion

$q + 2q^{5} - 24q^{7} - 44q^{11} + 22q^{13} - 50q^{17} - 44q^{19} - 56q^{23} + O(q^{25})$

Coefficient field

The coefficients $a_n$ generate $\mathbb{Q}$ . The eigenvalue of $T = T_{5} + 2T_{7} + 3T_{13} + 4T_{17} + 5T_{19} + 6T_{11} + 7T_{23} + 8T_{29}$ is a root of

$x + 2640$

Atkin–Lehner signs

$p$	$w_p$
2	— ( $2^2 \mid 144$ )
3	— ( $3^2 \mid 144$ )

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 0.303 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.
