Newform orbit 36.10.a.a

$q$ -expansion

$q - 990q^{5} + 8576q^{7} - 70596q^{11} - 2530q^{13} + 200574q^{17} - 695620q^{19} - 2472696q^{23} + O(q^{25})$

Coefficient field

The coefficients $a_n$ generate $\mathbb{Q}$ . The eigenvalue of $T = T_{5} + T_{7}$ is a root of

$x - 7586$

Atkin–Lehner signs

$p$	$w_p$
2	— ( $2^2 \mid 36$ )
3	— ( $3^2 \mid 36$ )

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

Sato–Tate

The normalized $a_p / 2p^{9/2}$ for the primes $p < 1000$ not dividing 36, against the semicircle $\tfrac{2}{\pi}\sqrt{1 - x^2}$ :

Provenance

Stored in the atlas: computed by Sagebrush's modular symbols engine in 0.344 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, 6, 9, 12, 18, 36]: [1, 3, 4, 6, 11, 10, 21, 29, 57] (certified at ell = 2147483647)
T = [(5, 1), (7, 1)]; h of degree 4 = 1 x 4 (phi(ord eps) x dim S_k^new); 2 primes, 0 rejected
