Decomposition of the old subspace
Provenance
Stored in the atlas: computed by Sagebrush's modular symbols engine in 0.381 s (one thread) and proven: the dimensions are certified, and the characteristic polynomial of over is reconstructed by CRT past a rigorous coefficient bound.
The engine's checks
dim M^+ at levels [1, 2, 4, 8, 16, 37, 74, 148, 296, 592]: [0, 1, 2, 3, 4, 3, 11, 22, 42, 80] (certified at ell = 2147483629)T = [(3, 1), (5, 3), (7, 5), (11, 7), (13, 9)]; h of degree 18 = 1 x 18 (phi(ord eps) x dim S_k^new); 5 primes, 0 rejected
