\(f(q)\) \(=\) \( q + \zeta_{6} q^{5} + ( 2 + \zeta_{6} ) q^{7} +O(q^{10})\) \( q + \zeta_{6} q^{5} + ( 2 + \zeta_{6} ) q^{7} + ( -2 + 2 \zeta_{6} ) q^{11} + q^{13} + ( -4 + 4 \zeta_{6} ) q^{17} + \zeta_{6} q^{19} + 4 \zeta_{6} q^{23} + ( -1 + \zeta_{6} ) q^{25} + ( 5 - 5 \zeta_{6} ) q^{31} + ( -1 + 3 \zeta_{6} ) q^{35} + 5 \zeta_{6} q^{37} -2 q^{41} -9 q^{43} -2 \zeta_{6} q^{47} + ( 3 + 5 \zeta_{6} ) q^{49} + ( 12 - 12 \zeta_{6} ) q^{53} -2 q^{55} + ( -8 + 8 \zeta_{6} ) q^{59} + 14 \zeta_{6} q^{61} + \zeta_{6} q^{65} + ( -9 + 9 \zeta_{6} ) q^{67} -2 q^{71} + ( -1 + \zeta_{6} ) q^{73} + ( -6 + 4 \zeta_{6} ) q^{77} + 3 \zeta_{6} q^{79} + 18 q^{83} -4 q^{85} -4 \zeta_{6} q^{89} + ( 2 + \zeta_{6} ) q^{91} + ( -1 + \zeta_{6} ) q^{95} + 10 q^{97} +O(q^{100})\)
