Rule: Q[1, 4, 12]

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.

• $P_1$:
  $t$
• $P_2$:
  $t^5-\frac{10}{9}\cdot t^3+\frac{5}{21}\cdot t$
• $P_3$:
  $t^{17}-\frac{8857204}{2038671}\cdot t^{15}+\frac{28927370}{3714291}\cdot t^{13}-\frac{6039926464}{813429729}\cdot t^{11}+\frac{9865688404}{2440289187}\cdot t^9-\frac{11887949788}{9490013505}\cdot t^7+\frac{122410578862}{592447985955}\cdot t^5-\frac{5464102072}{355468791573}\cdot t^3+\frac{39745277}{118489597191}\cdot t$
