Hecke eigenvalues ($q$-expansion)
The Hecke eigenvalue field is $\Q(e)$ where $e$ is a root of the defining polynomial:
\(x^{23} - 2x^{22} - 53x^{21} + 102x^{20} + 1211x^{19} - 2207x^{18} - 15684x^{17} + 26463x^{16} + 127465x^{15} - 192791x^{14} - 680274x^{13} + 880397x^{12} + 2423734x^{11} - 2506491x^{10} - 5731973x^{9} + 4259090x^{8} + 8733548x^{7} - 3850250x^{6} - 8028594x^{5} + 1235189x^{4} + 3856635x^{3} + 339195x^{2} - 655130x - 154628\) |
