For pβˆ₯Np \parallel N every form in the orbit has ap=βˆ’pk/2βˆ’1wpa_p = -p^{k/2-1} w_p.

Elliptic curve

By modularity this newform is the one attached to the isogeny class 600.i (Cremona's 600i). Its optimal curve 600i1 is

y2=x3+x2+167xβˆ’37y^2 = x^3 + x^2 + 167x - 37

of rank 0 with torsion of order 1. Its apa_p, computed by Sagebrush's point-counting engine, equal the newform's for every prime p<1000p < 1000.

Provenance

Stored in the atlas: computed by Sagebrush's modular symbols engine in 2.027 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.
