$q$-expansion

Coefficients of the $q$-expansion are expressed in terms of a primitive root of unity $\zeta_{24}$. We also show the integral $q$-expansion of the trace form.

$f(q)$	$=$	$ q + ( - \zeta_{24}^{6} + \zeta_{24}^{4}) q^{2} + (\zeta_{24}^{7} + \zeta_{24}^{4} + \cdots - 1) q^{3}+ \cdots + ( - 2 \zeta_{24}^{7} + \cdots - 2 \zeta_{24}) q^{9}+O(q^{10}) $ q + (-z^6 + z^4) * q^2 + (z^7 + z^4 - z^3 + z^2 - 1) * q^3 + (z^4 - 2) * q^4 + (z^6 + z^5 - z^4 - z^3 + z^2) * q^6 + (2z^7 - 4z^3 + z) * q^7 + (z^6 + z^4 - z^2 - 1) * q^8 + (-2z^7 + z^6 - z^2 - 2z) * q^9	$ q + ( - \zeta_{24}^{6} + \zeta_{24}^{4}) q^{2} + (\zeta_{24}^{7} + \zeta_{24}^{4} + \cdots - 1) q^{3}+ \cdots + (8 \zeta_{24}^{6} + \cdots + 2 \zeta_{24}) q^{99}+O(q^{100}) $ q + (-z^6 + z^4) * q^2 + (z^7 + z^4 - z^3 + z^2 - 1) * q^3 + (z^4 - 2) * q^4 + (z^6 + z^5 - z^4 - z^3 + z^2) * q^6 + (2z^7 - 4z^3 + z) * q^7 + (z^6 + z^4 - z^2 - 1) * q^8 + (-2z^7 + z^6 - z^2 - 2z) * q^9 + (2z^7 - 2z^5 - 2z^3) q^11 + (-2z^7 + z^6 - 2z^4 + z^3 - 2z^2 + 1) q^12 + (-3z^5 + 2z^3 + 3z) q^13 + (-3z^7 + 5z^5 - 2z^3 - 2z) * q^14 + (-4z^6 + z^4 + 2z^2 - 1) * q^16 + (-2z^6 - 2z^4 + 2z^2) q^17 + (-2z^5 + z^4 + 2z^3 - z^2 - 2z) q^18 + (-4z^6 + z^4 + 4z^2 - 2) * q^19 + (-4z^7 - 2z^6 - z^5 + 3z^3 + 4z^2 - 3z - 1) q^21 + (2z^7 - 4z^3 + 2z) q^22 + (5z^4 + 5z^2 - 5) * q^23 + (-z^7 - z^5 - z^4 - z^2 + z - 1) * q^24 + (2z^7 - 2z^5 - 3z^3 + 5z) * q^26 + (z^6 - 5z^5 + 5z + 1) * q^27 + (-6z^7 + z^5 + 6z^3 - 2z) q^28 + (-5z^7 - 5z^5 + 5z^3) q^29 + (4z^6 - 8z^2) * q^31 + (-4z^6 - 4z^4 + 5z^2 - 1) q^32 + (-4z^7 - 2z^6 + 2z^4 + 2z^2) * q^33 + (2z^6 - 4z^4 + 2) * q^34 + (2z^7 - 2z^6 - 2z^5 + 2z^3 + z^2 + 4z) q^36 + (2z^7 - 4z^5 + 2z^3) q^37 + (z^6 - 5z^4 + 5z^2 - 1) * q^38 + (-z^7 + 5z^5 + 3z^4 + z^3 - 2z^2 - 3) q^39 + (-2z^7 + 2z^5 + 2z^3) q^41 + (3z^7 + 3z^6 - 7z^5 - 5z^4 + 3z^3 + 2z^2 + 2) * q^42 + z^7 * q^43 + (-4z^7 + 2z^5 + 2z^3 + 2z) * q^44 + (5z^6 - 5z^4 + 5z^2) q^46 + (6z^6 + 6) q^47 + (-z^7 + 3z^6 + 4z^5 - 3z^4 + z^2 - 2z + 4) * q^48 + (-4z^4 + 6z^2 - 4) * q^49 + (2z^5 + 2z^3 - 2z + 4) q^51 + (2z^7 + 6z^5 - 4z^3 - 3z) * q^52 + (-3z^6 - 6z^4 + 6z^2 + 3) q^53 + (z^4 - 5z^3 - z^2 + 5z + 1) * q^54 + (-3z^7 - z^5 + z^3 + 3z) * q^56 + (-2z^7 + 5z^6 + 4z^5 - 2z^4 + z^3 - 2z^2 - 4z + 5) * q^57 + (5z^7 - 10z^5 + 5z) q^58 + (z^7 - 6z^5 - 6z^3 + z) * q^59 + (-4z^6 - 4z^4 - 4z^2) q^61 + (-4z^6 + 8z^4 - 4z^2 - 4) q^62 + (z^7 + 8z^6 - 2z^5 + 2z^4 - z^3 - 6z^2 + 4z + 6) q^63 + (4z^6 - 2z^4 + 1) * q^64 + (-4z^7 - 2z^6 + 4z^3 + 4z^2 - 4z - 2) q^66 + (-4z^7 - z^5 - 4z^3) * q^67 + (4z^6 + 2z^4 - 2z^2 + 2) q^68 + (-5z^7 + 10z^6 - 10z^2 - 5z) * q^69 + (6z^7 + 4z^5 - 4z^3 - 6z) * q^71 + (-2z^7 - z^6 - z^4 + 4z^3 + 2z + 1) q^72 + (z^5 + z) * q^73 + (8z^7 - 6z^5 - 6z^3 + 8z) * q^74 + (8z^6 - 3z^4 - 4z^2 + 3) q^76 + (-6z^6 + 8z^4 + 8z^2 - 6) q^77 + (-5z^7 - 2z^6 + 4z^5 + 2z^4 + 6z^3 + 3z^2 - 5z - 5) q^78 + (-6z^6 - 6z^4 + 3) * q^79 + (-4z^7 + 4z^5 + 7z^4 + 4z^3 - 7) * q^81 + (-2z^7 + 4z^3 - 2z) q^82 + (-5z^6 - 4z^4 + 4z^2 + 5) q^83 + (7z^7 + 6z^6 - 2z^5 - z^4 - 2z^3 - 6z^2 + 7z + 2) * q^84 + (z^7 - z^3 + z) * q^86 + (5z^6 + 5z^4 - 5z^2 + 10z) * q^87 + (-2z^7 - 2z^5 + 2z^3 + 4z) * q^88 + (-3z^7 - 3z^5 - z^3 + 4z) q^89 + (-7z^6 + 8z^4 - z^2 - 12) * q^91 + (5z^6 - 10z^4 - 10z^2 + 5) q^92 + (-8z^6 - 4z^5 - 4z^4 + 4z^2 + 8z - 4) q^93 + (6z^4 - 6z^2 + 6) * q^94 + (-z^7 + z^6 + 4z^5 + 5z^3 - 2z^2 - 5z + 9) * q^96 + (2z^7 - 4z^3 - 8z) q^97 + (14z^6 - 14z^4 - 4z^2 + 10) q^98 + (8z^6 - 2z^5 + 2z^3 + 2z) * q^99
