Hecke eigenvalues ($q$-expansion)

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

\(x^{34} + 6x^{33} - 64x^{32} - 424x^{31} + 1770x^{30} + 13292x^{29} - 27918x^{28} - 245359x^{27} + 279741x^{26} + 2984856x^{25} - 1887901x^{24} - 25363915x^{23} + 9020266x^{22} + 155522086x^{21} - 33007342x^{20} - 699955090x^{19} + 105465900x^{18} + 2325984857x^{17} - 323151722x^{16} - 5685880095x^{15} + 878189527x^{14} + 10090669043x^{13} - 1813609905x^{12} - 12693014291x^{11} + 2537362006x^{10} + 10894619315x^{9} - 2185785281x^{8} - 6016229092x^{7} + 998123180x^{6} + 1946184690x^{5} - 153475734x^{4} - 310007709x^{3} - 16784172x^{2} + 12803090x + 1214263\)
