Hecke eigenvalues ($q$-expansion)

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

\(x^{16} + x^{15} - 23x^{14} - 21x^{13} + 208x^{12} + 169x^{11} - 944x^{10} - 658x^{9} + 2265x^{8} + 1281x^{7} - 2725x^{6} - 1119x^{5} + 1322x^{4} + 277x^{3} - 87x^{2} - 10x + 1\)
