$q$ -expansion

$q - 2q^{2} - 3q^{3} + 4q^{4} + 6q^{6} + 4q^{7} - 8q^{8} + 9q^{9} - 48q^{11} - 12q^{12} - 2q^{13} - 8q^{14} + 16q^{16} + 114q^{17} - 18q^{18} + 140q^{19} - 12q^{21} + 96q^{22} - 72q^{23} + 24q^{24} + O(q^{25})$

Coefficient field

The coefficients $a_n$ generate $\mathbb{Q}$ . The eigenvalue of $T = T_{7} + 3T_{11}$ is a root of

$x + 140$

Atkin–Lehner signs

$p$	$w_p$
2	$+1$
3	$+1$
5	— ( $5^2 \mid 150$ )

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

Provenance

Stored in the atlas: computed by Sagebrush's modular symbols engine in 0.174 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, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150]: [1, 2, 2, 3, 5, 7, 8, 9, 22, 25, 32, 94] (certified at ell = 2147482921)
T = [(7, 1), (11, 3)]; h of degree 9 = 1 x 9 (phi(ord eps) x dim S_k^new); 3 primes, 0 rejected
