$q$ -expansion

$q - 2q^{2} - 9q^{3} - 28q^{4} + 46q^{5} + 18q^{6} + 148q^{7} + 120q^{8} + 81q^{9} - 92q^{10} + 121q^{11} + 252q^{12} + 574q^{13} - 296q^{14} - 414q^{15} + 656q^{16} - 722q^{17} - 162q^{18} + 2160q^{19} - 1288q^{20} - 1332q^{21} - 242q^{22} - 2536q^{23} - 1080q^{24} + O(q^{25})$

Coefficient field

The coefficients $a_n$ generate $\mathbb{Q}$ . The eigenvalue of $T = T_{2} + T_{5}$ is a root of

$x - 44$

Atkin–Lehner signs

$p$	$w_p$
3	$+1$
11	$-1$

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 0.227 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, 3, 11, 33]: [1, 3, 6, 22] (certified at ell = 2147483171)
T = [(2, 1), (5, 1)]; h of degree 8 = 1 x 8 (phi(ord eps) x dim S_k^new); 2 primes, 0 rejected
