Newform orbit 134.4.a.a

$q$ -expansion

$q + 2q^{2} + 10q^{3} + 4q^{4} + 6q^{5} + 20q^{6} - 34q^{7} + 8q^{8} + 73q^{9} + 12q^{10} + 24q^{11} + 40q^{12} - 46q^{13} - 68q^{14} + 60q^{15} + 16q^{16} - 69q^{17} + 146q^{18} - 79q^{19} + 24q^{20} - 340q^{21} + 48q^{22} + 99q^{23} + 80q^{24} + O(q^{25})$

Coefficient field

The coefficients $a_n$ generate $\mathbb{Q}$ . The eigenvalue of $T = T_{3} + T_{5}$ is a root of

$x - 16$

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.

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)
