## $q$-expansion

Coefficients of the $$q$$-expansion are expressed in terms of a basis $$1,\beta_1,\beta_2,\beta_3$$ for the coefficient ring described below. We also show the integral $$q$$-expansion of the trace form.

 $$f(q)$$ $$=$$ $$q + \beta_{1} q^{2} + ( 1 + \beta_{2} ) q^{4} + ( -1 + 2 \beta_{2} ) q^{7} + ( \beta_{1} + \beta_{3} ) q^{8} +O(q^{10})$$ $$q + \beta_{1} q^{2} + ( 1 + \beta_{2} ) q^{4} + ( -1 + 2 \beta_{2} ) q^{7} + ( \beta_{1} + \beta_{3} ) q^{8} -2 \beta_{3} q^{11} + ( -\beta_{1} + 2 \beta_{3} ) q^{14} + ( -1 + 3 \beta_{2} ) q^{16} + ( 4 - 4 \beta_{2} ) q^{22} -4 \beta_{3} q^{23} + 5 q^{25} + ( -5 + 3 \beta_{2} ) q^{28} + ( -8 \beta_{1} + 2 \beta_{3} ) q^{29} + ( -\beta_{1} + 3 \beta_{3} ) q^{32} -6 q^{37} + ( 2 - 4 \beta_{2} ) q^{43} + ( 4 \beta_{1} - 4 \beta_{3} ) q^{44} + ( 8 - 8 \beta_{2} ) q^{46} -7 q^{49} + 5 \beta_{1} q^{50} + ( 8 \beta_{1} - 2 \beta_{3} ) q^{53} + ( -5 \beta_{1} + 3 \beta_{3} ) q^{56} + ( -12 - 4 \beta_{2} ) q^{58} + ( -7 + 5 \beta_{2} ) q^{64} + ( 6 - 12 \beta_{2} ) q^{67} + 8 \beta_{3} q^{71} -6 \beta_{1} q^{74} + ( 8 \beta_{1} - 2 \beta_{3} ) q^{77} + ( -6 + 12 \beta_{2} ) q^{79} + ( 2 \beta_{1} - 4 \beta_{3} ) q^{86} + ( 12 - 4 \beta_{2} ) q^{88} + ( 8 \beta_{1} - 8 \beta_{3} ) q^{92} -7 \beta_{1} q^{98} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$4q + 6q^{4} + O(q^{10})$$ $$4q + 6q^{4} + 2q^{16} + 8q^{22} + 20q^{25} - 14q^{28} - 24q^{37} + 16q^{46} - 28q^{49} - 56q^{58} - 18q^{64} + 40q^{88} + O(q^{100})$$

Basis of coefficient ring in terms of a root $$\nu$$ of $$x^{4} - 3 x^{2} + 4$$:

 $$\beta_{0}$$ $$=$$ $$1$$ $$\beta_{1}$$ $$=$$ $$\nu$$ $$\beta_{2}$$ $$=$$ $$\nu^{2} - 1$$ $$\beta_{3}$$ $$=$$ $$\nu^{3} - \nu$$
 $$1$$ $$=$$ $$\beta_0$$ $$\nu$$ $$=$$ $$\beta_{1}$$ $$\nu^{2}$$ $$=$$ $$\beta_{2} + 1$$ $$\nu^{3}$$ $$=$$ $$\beta_{3} + \beta_{1}$$

## Character values

We give the values of $$\chi$$ on generators for $$\left(\mathbb{Z}/252\mathbb{Z}\right)^\times$$.

 $$n$$ $$29$$ $$73$$ $$127$$ $$\chi(n)$$ $$1$$ $$-1$$ $$-1$$
