Hecke eigenvalues ($q$-expansion)

The Hecke eigenvalue field is $\Q(e)$ where $e$ is a root of the defining polynomial:

\(x^{40} - 10x^{39} - 11x^{38} + 422x^{37} - 715x^{36} - 7574x^{35} + 23950x^{34} + 72347x^{33} - 357292x^{32} - 339984x^{31} + 3249778x^{30} - 180864x^{29} - 19824156x^{28} + 13892601x^{27} + 84156991x^{26} - 102416693x^{25} - 249952936x^{24} + 436224332x^{23} + 504484109x^{22} - 1252557065x^{21} - 618154040x^{20} + 2534280592x^{19} + 218633196x^{18} - 3648854489x^{17} + 705129588x^{16} + 3700784293x^{15} - 1499336791x^{14} - 2564347960x^{13} + 1508973647x^{12} + 1138412832x^{11} - 897866034x^{10} - 278539949x^{9} + 316156339x^{8} + 19174925x^{7} - 60303202x^{6} + 5194142x^{5} + 5134397x^{4} - 819142x^{3} - 147517x^{2} + 27557x + 335\)
