Newform invariants
Coefficients of the \(q\)-expansion are expressed in terms of a basis \(1,\beta_1,\ldots,\beta_{7}\) for the coefficient ring described below.
We also show the integral \(q\)-expansion of the trace form.
Basis of coefficient ring in terms of a root \(\nu\) of \(x^{8} + 14 x^{6} + 61 x^{4} + 84 x^{2} + 4\):
| \(\beta_{0}\) | \(=\) | \( 1 \) |
| \(\beta_{1}\) | \(=\) | \((\)\( \nu^{5} + 9 \nu^{3} + 16 \nu \)\()/2\) |
| \(\beta_{2}\) | \(=\) | \((\)\( \nu^{6} + 11 \nu^{4} + 30 \nu^{2} + 4 \nu + 12 \)\()/4\) |
| \(\beta_{3}\) | \(=\) | \((\)\( -\nu^{6} - 9 \nu^{4} - 16 \nu^{2} + 2 \)\()/2\) |
| \(\beta_{4}\) | \(=\) | \((\)\( -\nu^{6} - 11 \nu^{4} - 30 \nu^{2} + 4 \nu - 12 \)\()/4\) |
| \(\beta_{5}\) | \(=\) | \((\)\( \nu^{5} + 11 \nu^{3} + 26 \nu \)\()/2\) |

| \(1\) | \(=\) | \(\beta_0\) |
| \(\nu\) | \(=\) | \((\)\(\beta_{4} + \beta_{2}\)\()/2\) |
| \(\nu^{2}\) | \(=\) | \((\)\(\beta_{6} - \beta_{4} + \beta_{2} - 8\)\()/2\) |
| \(\nu^{3}\) | \(=\) | \((\)\(2 \beta_{5} - 5 \beta_{4} - 5 \beta_{2} - 2 \beta_{1}\)\()/2\) |
| \(\nu^{4}\) | \(=\) | \((\)\(-7 \beta_{6} + 5 \beta_{4} + 2 \beta_{3} - 5 \beta_{2} + 42\)\()/2\) |
| \(\nu^{5}\) | \(=\) | \((\)\(-18 \beta_{5} + 29 \beta_{4} + 29 \beta_{2} + 22 \beta_{1}\)\()/2\) |
| \(\nu^{6}\) | \(=\) | \((\)\(47 \beta_{6} - 29 \beta_{4} - 22 \beta_{3} + 29 \beta_{2} - 246\)\()/2\) |
