Newform orbit 952.2.a.e

Trace form

The 3 newforms in this orbit are conjugate over $\mathbb{Q}$ ; the sum of their $q$ -expansions is

$3q - q^{3} + 3q^{5} - 3q^{7} + 6q^{9} + 6q^{11} + 6q^{13} - 3q^{17} - 12q^{19} + q^{21} + 2q^{23} + O(q^{25})$

Coefficient field

The coefficients $a_n$ generate a number field of degree 3. It is generated by the eigenvalue $\alpha$ of $T = T_{3} + 3T_{5}$ , whose minimal polynomial is

$x^{3} - 8x^{2} - 115x + 918$

Atkin–Lehner signs

Provenance

Stored in the atlas: computed by Sagebrush's modular symbols engine in 0.588 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 label, dimension and $\operatorname{tr} a_p$ for every $p < 1000$ equal LMFDB's.
