Hecke eigenvalues ($q$-expansion)

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

\(x^{24} - 21x^{23} + 137x^{22} + 117x^{21} - 5345x^{20} + 18149x^{19} + 45150x^{18} - 392175x^{17} + 336664x^{16} + 3063664x^{15} - 7348822x^{14} - 9002368x^{13} + 46187727x^{12} - 6256324x^{11} - 144456207x^{10} + 103883252x^{9} + 249122160x^{8} - 259585548x^{7} - 245763642x^{6} + 286192158x^{5} + 143573041x^{4} - 130950072x^{3} - 47081024x^{2} + 8218496x + 528128\)
