## $q$-expansion

Coefficients of the $$q$$-expansion are expressed in terms of a primitive root of unity $$\zeta_{10}$$. We also show the integral $$q$$-expansion of the trace form.

 $$f(q)$$ $$=$$ $$q + ( - \zeta_{10}^{3} + \zeta_{10}^{2} + \cdots + 1) q^{2}+ \cdots + (\zeta_{10}^{3} - \zeta_{10}^{2} + \cdots - 1) q^{9}+O(q^{10})$$ q + (-z^3 + z^2 - z + 1) * q^2 - z^2 * q^3 + z^3 * q^4 + 2*z * q^5 - z * q^6 + 4*z^3 * q^7 + 3*z^2 * q^8 + (z^3 - z^2 + z - 1) * q^9 $$q + ( - \zeta_{10}^{3} + \zeta_{10}^{2} + \cdots + 1) q^{2}+ \cdots - 9 q^{98}+O(q^{100})$$ q + (-z^3 + z^2 - z + 1) * q^2 - z^2 * q^3 + z^3 * q^4 + 2*z * q^5 - z * q^6 + 4*z^3 * q^7 + 3*z^2 * q^8 + (z^3 - z^2 + z - 1) * q^9 + 2 * q^10 + q^12 + (2*z^3 - 2*z^2 + 2*z - 2) * q^13 + 4*z^2 * q^14 - 2*z^3 * q^15 + z * q^16 - 2*z * q^17 + z^3 * q^18 + (2*z^3 - 2*z^2 + 2*z - 2) * q^20 + 4 * q^21 + 8 * q^23 + (-3*z^3 + 3*z^2 - 3*z + 3) * q^24 - z^2 * q^25 + 2*z^3 * q^26 + z * q^27 - 4*z * q^28 - 6*z^3 * q^29 - 2*z^2 * q^30 + (-8*z^3 + 8*z^2 - 8*z + 8) * q^31 - 5 * q^32 - 2 * q^34 + (8*z^3 - 8*z^2 + 8*z - 8) * q^35 - z^2 * q^36 - 6*z^3 * q^37 + 2*z * q^39 + 6*z^3 * q^40 + 2*z^2 * q^41 + (-4*z^3 + 4*z^2 - 4*z + 4) * q^42 - 2 * q^45 + (-8*z^3 + 8*z^2 - 8*z + 8) * q^46 + 8*z^2 * q^47 - z^3 * q^48 - 9*z * q^49 - z * q^50 + 2*z^3 * q^51 - 2*z^2 * q^52 + (6*z^3 - 6*z^2 + 6*z - 6) * q^53 + q^54 - 12 * q^56 - 6*z^2 * q^58 + 4*z^3 * q^59 + 2*z * q^60 + 6*z * q^61 - 8*z^3 * q^62 - 4*z^2 * q^63 + (7*z^3 - 7*z^2 + 7*z - 7) * q^64 - 4 * q^65 - 4 * q^67 + (-2*z^3 + 2*z^2 - 2*z + 2) * q^68 - 8*z^2 * q^69 + 8*z^3 * q^70 - 3*z * q^72 - 14*z^3 * q^73 - 6*z^2 * q^74 + (z^3 - z^2 + z - 1) * q^75 + 2 * q^78 + (4*z^3 - 4*z^2 + 4*z - 4) * q^79 + 2*z^2 * q^80 - z^3 * q^81 + 2*z * q^82 + 12*z * q^83 + 4*z^3 * q^84 - 4*z^2 * q^85 - 6 * q^87 - 6 * q^89 + (2*z^3 - 2*z^2 + 2*z - 2) * q^90 - 8*z^2 * q^91 + 8*z^3 * q^92 - 8*z * q^93 + 8*z * q^94 + 5*z^2 * q^96 + (2*z^3 - 2*z^2 + 2*z - 2) * q^97 - 9 * q^98 $$\operatorname{Tr}(f)(q)$$ $$=$$ $$4 q + q^{2} + q^{3} + q^{4} + 2 q^{5} - q^{6} + 4 q^{7} - 3 q^{8} - q^{9}+O(q^{10})$$ 4 * q + q^2 + q^3 + q^4 + 2 * q^5 - q^6 + 4 * q^7 - 3 * q^8 - q^9 $$4 q + q^{2} + q^{3} + q^{4} + 2 q^{5} - q^{6} + 4 q^{7} - 3 q^{8} - q^{9} + 8 q^{10} + 4 q^{12} - 2 q^{13} - 4 q^{14} - 2 q^{15} + q^{16} - 2 q^{17} + q^{18} - 2 q^{20} + 16 q^{21} + 32 q^{23} + 3 q^{24} + q^{25} + 2 q^{26} + q^{27} - 4 q^{28} - 6 q^{29} + 2 q^{30} + 8 q^{31} - 20 q^{32} - 8 q^{34} - 8 q^{35} + q^{36} - 6 q^{37} + 2 q^{39} + 6 q^{40} - 2 q^{41} + 4 q^{42} - 8 q^{45} + 8 q^{46} - 8 q^{47} - q^{48} - 9 q^{49} - q^{50} + 2 q^{51} + 2 q^{52} - 6 q^{53} + 4 q^{54} - 48 q^{56} + 6 q^{58} + 4 q^{59} + 2 q^{60} + 6 q^{61} - 8 q^{62} + 4 q^{63} - 7 q^{64} - 16 q^{65} - 16 q^{67} + 2 q^{68} + 8 q^{69} + 8 q^{70} - 3 q^{72} - 14 q^{73} + 6 q^{74} - q^{75} + 8 q^{78} - 4 q^{79} - 2 q^{80} - q^{81} + 2 q^{82} + 12 q^{83} + 4 q^{84} + 4 q^{85} - 24 q^{87} - 24 q^{89} - 2 q^{90} + 8 q^{91} + 8 q^{92} - 8 q^{93} + 8 q^{94} - 5 q^{96} - 2 q^{97} - 36 q^{98}+O(q^{100})$$ 4 * q + q^2 + q^3 + q^4 + 2 * q^5 - q^6 + 4 * q^7 - 3 * q^8 - q^9 + 8 * q^10 + 4 * q^12 - 2 * q^13 - 4 * q^14 - 2 * q^15 + q^16 - 2 * q^17 + q^18 - 2 * q^20 + 16 * q^21 + 32 * q^23 + 3 * q^24 + q^25 + 2 * q^26 + q^27 - 4 * q^28 - 6 * q^29 + 2 * q^30 + 8 * q^31 - 20 * q^32 - 8 * q^34 - 8 * q^35 + q^36 - 6 * q^37 + 2 * q^39 + 6 * q^40 - 2 * q^41 + 4 * q^42 - 8 * q^45 + 8 * q^46 - 8 * q^47 - q^48 - 9 * q^49 - q^50 + 2 * q^51 + 2 * q^52 - 6 * q^53 + 4 * q^54 - 48 * q^56 + 6 * q^58 + 4 * q^59 + 2 * q^60 + 6 * q^61 - 8 * q^62 + 4 * q^63 - 7 * q^64 - 16 * q^65 - 16 * q^67 + 2 * q^68 + 8 * q^69 + 8 * q^70 - 3 * q^72 - 14 * q^73 + 6 * q^74 - q^75 + 8 * q^78 - 4 * q^79 - 2 * q^80 - q^81 + 2 * q^82 + 12 * q^83 + 4 * q^84 + 4 * q^85 - 24 * q^87 - 24 * q^89 - 2 * q^90 + 8 * q^91 + 8 * q^92 - 8 * q^93 + 8 * q^94 - 5 * q^96 - 2 * q^97 - 36 * q^98
