Newform orbit 529.2.a.j

Trace form

The 5 newforms in this orbit are conjugate over $\mathbb{Q}$ ; the sum of their $q$ -expansions is

$5q + 2q^{2} + 2q^{3} + 4q^{4} + 7q^{5} - 8q^{6} + 8q^{7} - 9q^{8} - q^{9} + 5q^{10} + 13q^{11} - 5q^{12} + 4q^{13} + 12q^{14} + 5q^{15} + 6q^{16} + 16q^{17} + 4q^{18} + 10q^{19} + 10q^{20} + q^{21} + 3q^{22} - 19q^{24} + O(q^{25})$

Coefficient field

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

$x^{5} - 216x^{4} + 18350x^{3} - 768289x^{2} + 15881754x - 129851479$

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

Provenance

Stored in the atlas: computed by Sagebrush's modular symbols engine in 0.208 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.

The engine's checks

dim M^+ at levels [1, 23, 529]: [0, 3, 47] (certified at ell = 2147474627)
T = [(2, 1), (3, 3), (5, 5), (7, 7), (11, 9)]; h of degree 31 = 1 x 31 (phi(ord eps) x dim S_k^new); 8 primes, 0 rejected
