$q$ -expansion

$q - 27q^{3} - 125q^{5} + 1028q^{7} + 729q^{9} + 3096q^{11} - 13030q^{13} + 3375q^{15} + 1878q^{17} - 31180q^{19} - 27756q^{21} - 33288q^{23} + O(q^{25})$

Coefficient field

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

$x - 4124$

Atkin–Lehner signs

$p$	$w_p$
2	— ( $2^2 \mid 60$ )
3	$+1$
5	$+1$

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

Sato–Tate

The normalized $a_p / 2p^{7/2}$ for the primes $p < 1000$ not dividing 60, against the semicircle $\tfrac{2}{\pi}\sqrt{1 - x^2}$ :

Provenance

Stored in the atlas: computed by Sagebrush's modular symbols engine in 0.362 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, 4, 5, 6, 10, 12, 15, 20, 30, 60]: [1, 3, 3, 5, 5, 9, 13, 17, 16, 24, 46, 90] (certified at ell = 2147483629)
T = [(7, 1), (11, 1)]; h of degree 4 = 1 x 4 (phi(ord eps) x dim S_k^new); 2 primes, 0 rejected
