Hecke eigenvalues ($q$-expansion)
The Hecke eigenvalue field is $\Q(e)$ where $e$ is a root of the defining polynomial:
\(x^{39} + 2x^{38} - 96x^{37} - 180x^{36} + 4201x^{35} + 7320x^{34} - 111083x^{33} - 178179x^{32} + 1982867x^{31} + 2898584x^{30} - 25277156x^{29} - 33324178x^{28} + 237349425x^{27} + 279257347x^{26} - 1668614198x^{25} - 1735007118x^{24} + 8838368734x^{23} + 8057692004x^{22} - 35216286172x^{21} - 28034041673x^{20} + 104638293843x^{19} + 72901624152x^{18} - 228220201161x^{17} - 140764790322x^{16} + 356901679915x^{15} + 199120624825x^{14} - 387505342619x^{13} - 200854317166x^{12} + 279891060515x^{11} + 137389816085x^{10} - 127281070207x^{9} - 58929466554x^{8} + 34089090706x^{7} + 14351771879x^{6} - 4864407338x^{5} - 1694988485x^{4} + 306641353x^{3} + 68873322x^{2} - 5245834x - 625625\) |
