Rule: Q[2, 6, 8]

Type

Polynomials

One starts from the polynomial $P_1$ and extends one by one with $P_{\mathrm{i}}$ until the final polynomial defining this rule is reached.
Note: Polynomials might be truncated due to size! The complete polynomials are included in the download.

• $P_1$:
  $\frac{3}{2}\cdot t^2-\frac{1}{2}$
• $P_2$:
  $\frac{3}{2}\cdot t^8-\frac{161}{52}\cdot t^6+\frac{105}{52}\cdot t^4-\frac{245}{572}\cdot t^2+\frac{25}{1716}$
• $P_3$:
  $\frac{3}{2}\cdot t^{16}-\frac{52675}{9724}\cdot t^{14}+\frac{62424565}{7972932}\cdot t^{12}-\frac{25786918405}{4472814852}\cdot t^{10}+\frac{2493674299078805}{1096541870671764}\cdot t^8-\frac{66130895817287}{143027200522404}\cdot t^6+\frac{613871878555495}{14255044318732932}\cdot t^4-\frac{244523487906245}{156805487506062252}\cdot t^2+\frac{24672636591575}{1411249387554560268}$
