Newform orbit 484.2.a.e

Trace form

The 2 newforms in this orbit are conjugate over Q\mathbb{Q}; the sum of their qq-expansions is

2q+4q3+6q5+2q9+12q15βˆ’12q23+O(q25)2q + 4q^{3} + 6q^{5} + 2q^{9} + 12q^{15} - 12q^{23} + O(q^{25})

Coefficient field

The coefficients ana_n generate Q(3)\mathbb{Q}(\sqrt{3}). It is generated by the eigenvalue Ξ±\alpha of T=T3+3T5+5T7+7T13+9T17T = T_{3} + 3T_{5} + 5T_{7} + 7T_{13} + 9T_{17}, whose minimal polynomial is

Provenance

Stored in the atlas: computed by Sagebrush's modular symbols engine in 0.249 s (one thread) and proven: the dimensions are certified, and the characteristic polynomial of TT over Z\mathbb{Z} is reconstructed by CRT past a rigorous coefficient bound. The label, dimension and tr⁑ap\operatorname{tr} a_p for every p<1000p < 1000 equal LMFDB's.

The engine's checks
  • dim M^+ at levels [1, 2, 4, 11, 22, 44, 121, 242, 484]: [0, 1, 2, 2, 5, 9, 12, 35, 69] (certified at ell = 2147482921)
  • T = [(3, 1), (5, 3), (7, 5), (13, 7), (17, 9)]; h of degree 9 = 1 x 9 (phi(ord eps) x dim S_k^new); 3 primes, 0 rejected
