Newform orbit 735.2.a.n

Trace form

The 4 newforms in this orbit are conjugate over $\mathbb{Q}$ ; the sum of their $q$ -expansions is

$4q + 4q^{2} - 4q^{3} + 8q^{4} + 4q^{5} - 4q^{6} + 12q^{8} + 4q^{9} + 4q^{10} + 8q^{11} - 8q^{12} - 4q^{15} + 12q^{16} - 8q^{17} + 4q^{18} + 8q^{19} + 8q^{20} - 12q^{24} + O(q^{25})$

Coefficient field

The coefficients $a_n$ generate a number field of degree 4. It is generated by the eigenvalue $\alpha$ of $T = T_{2} + 3T_{11} + 5T_{13} + 7T_{17} + 9T_{19}$ , whose minimal polynomial is

$x^{4} - 44x^{3} - 520x^{2} - 1516x - 1279$

Atkin–Lehner signs

$p$	$w_p$
3	$+1$
5	$-1$
7	— ( $7^2 \mid 735$ )

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

$\operatorname{tr} a_n$ for every $n \le 1000$ is in the JSON.

Provenance

Stored in the atlas: computed by Sagebrush's modular symbols engine in 0.693 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.
