Newform orbit 134.4.a.d

Trace form

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

$5q + 10q^{2} + 2q^{3} + 20q^{4} + 3q^{5} + 4q^{6} + 69q^{7} + 40q^{8} + 49q^{9} + 6q^{10} + 25q^{11} + 8q^{12} + 108q^{13} + 138q^{14} + 73q^{15} + 80q^{16} + 159q^{17} + 98q^{18} + 163q^{19} + 12q^{20} - 36q^{21} + 50q^{22} - 105q^{23} + 16q^{24} + O(q^{25})$

Coefficient field

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

$x^{5} - 5x^{4} - 468x^{3} + 3186x^{2} + 8270x - 47329$

Atkin–Lehner signs

$p$	$w_p$
2	$-1$
67	$-1$

For $p \parallel N$ every form in the orbit has $a_p = -p^{k/2-1} w_p$ . The Fricke sign is $w_N = +1$ , so the sign of the functional equation is $(-1)^{k/2} w_N = +1$ : each L-function in the orbit has even analytic rank.

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

Provenance

Stored in the atlas: computed by Sagebrush's modular symbols engine in 0.111 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, 67, 134]: [1, 2, 18, 53] (certified at ell = 2147483647)
T = [(3, 1), (5, 1)]; h of degree 17 = 1 x 17 (phi(ord eps) x dim S_k^new); 3 primes, 0 rejected
