$q$-expansion

The dimension is sufficiently large that we do not compute an algebraic \(q\)-expansion, but we have computed the trace expansion.

\(\operatorname{Tr}(f)(q) = \) \( 21q + 10q^{3} - 3q^{5} + 15q^{7} + 21q^{9} + O(q^{10}) \)
\(\operatorname{Tr}(f)(q) = \) \( 21q + 10q^{3} - 3q^{5} + 15q^{7} + 21q^{9} + 9q^{11} - 16q^{13} + 22q^{15} + q^{17} + 12q^{19} - 2q^{21} + 22q^{23} + 18q^{25} + 43q^{27} - 13q^{29} + 28q^{31} + 3q^{33} + 12q^{35} - 39q^{37} + 11q^{39} + 4q^{41} + 50q^{43} - 6q^{45} + 27q^{47} + 16q^{49} + 37q^{51} - 24q^{53} + 49q^{55} - q^{57} + 22q^{59} - 22q^{61} + 49q^{63} - 14q^{65} + 62q^{67} - 17q^{69} + 21q^{71} - 6q^{73} + 52q^{75} - 24q^{77} + 65q^{79} + 29q^{81} + 18q^{83} - 54q^{85} + 31q^{87} + q^{89} + 45q^{91} - 26q^{93} + 53q^{95} - 2q^{97} + 58q^{99} + O(q^{100}) \)
