Newform orbit 539.2.a.i

Trace form

The 3 newforms in this orbit are conjugate over Q\mathbb{Q}; the sum of their qq-expansions is

Coefficient field

The coefficients ana_n generate a number field of degree 3. It is generated by the eigenvalue Ξ±\alpha of T=T2+3T3+5T5+7T13T = T_{2} + 3T_{3} + 5T_{5} + 7T_{13}, whose minimal polynomial is

Provenance

Stored in the atlas: computed by Sagebrush's modular symbols engine in 0.338 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, 7, 11, 49, 77, 539]: [0, 1, 2, 5, 10, 58] (certified at ell = 2147482681)
  • T = [(2, 1), (3, 3), (5, 5), (13, 7)]; h of degree 34 = 1 x 34 (phi(ord eps) x dim S_k^new); 8 primes, 0 rejected
