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 TT over Z\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
