$q$-expansion

Copy content gp:mfcoefs(f, 20)
 

Coefficients of the \(q\)-expansion are expressed in terms of \(\beta = \sqrt{2}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + (\beta + 4) q^{2} + ( - 4 \beta + 1) q^{3} + (8 \beta + 10) q^{4} - 5 q^{5} + ( - 15 \beta - 4) q^{6} - 7 q^{7} + (34 \beta + 24) q^{8} + ( - 8 \beta + 6) q^{9} + ( - 5 \beta - 20) q^{10} + ( - 32 \beta - 7) q^{11}+ \cdots + ( - 136 \beta + 470) q^{99}+O(q^{100}) \) Copy content Toggle raw display
