\(f(q)\) \(=\) \( q - q^{5} + \zeta_{6} q^{7} +O(q^{10})\) \( q - q^{5} + \zeta_{6} q^{7} + ( 3 - 3 \zeta_{6} ) q^{11} + ( 3 - 4 \zeta_{6} ) q^{13} -3 \zeta_{6} q^{17} + 7 \zeta_{6} q^{19} + ( -3 + 3 \zeta_{6} ) q^{23} + q^{25} + ( 3 - 3 \zeta_{6} ) q^{29} -4 q^{31} -\zeta_{6} q^{35} + ( 7 - 7 \zeta_{6} ) q^{37} + ( -9 + 9 \zeta_{6} ) q^{41} -11 \zeta_{6} q^{43} + ( 6 - 6 \zeta_{6} ) q^{49} + 6 q^{53} + ( -3 + 3 \zeta_{6} ) q^{55} -3 \zeta_{6} q^{59} -11 \zeta_{6} q^{61} + ( -3 + 4 \zeta_{6} ) q^{65} + ( 7 - 7 \zeta_{6} ) q^{67} -3 \zeta_{6} q^{71} + 2 q^{73} + 3 q^{77} + 8 q^{79} + 12 q^{83} + 3 \zeta_{6} q^{85} + ( 15 - 15 \zeta_{6} ) q^{89} + ( 4 - \zeta_{6} ) q^{91} -7 \zeta_{6} q^{95} + 7 \zeta_{6} q^{97} +O(q^{100})\)
