Hecke eigenvalues ($q$-expansion)
The Hecke eigenvalue field is $\Q(e)$ where $e$ is a root of the defining polynomial:
\(x^{28} + 2x^{27} - 37x^{26} - 72x^{25} + 604x^{24} + 1144x^{23} - 5727x^{22} - 10548x^{21} + 34978x^{20} + 62406x^{19} - 144485x^{18} - 247362x^{17} + 413672x^{16} + 666220x^{15} - 831728x^{14} - 1212440x^{13} + 1184144x^{12} + 1456420x^{11} - 1195881x^{10} - 1100600x^{9} + 836759x^{8} + 470644x^{7} - 373418x^{6} - 83034x^{5} + 86110x^{4} - 3136x^{3} - 5004x^{2} + 380x + 44\) |
