Rule: Q[2, 4, 9]

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.

• $P_1$:
  $\frac{1}{2}\cdot t^2-2\cdot t+1$
• $P_2$:
  $\frac{1}{2}\cdot t^6-\frac{162}{13}\cdot t^5+101\cdot t^4-\frac{4208}{13}\cdot t^3+\frac{5436}{13}\cdot t^2-\frac{2928}{13}\cdot t+\frac{552}{13}$
• $P_3$:
  $\frac{1}{2}\cdot t^{15}-\frac{335476827161063738460038085879987}{2317239277355956082043188523626}\cdot t^{14}+\frac{85403978234682221205603073844621707}{5793098193389890205107971309065}\cdot t^{13}-\frac{895848123227788341674324195494363979}{1158619638677978041021594261813}\cdot t^{12}+\frac{698157082723792152300616016076248696124}{28965490966949451025539856545325}\cdot t^{11}-\frac{13840549741499437395021956207862287347572}{28965490966949451025539856545325}\cdot t^{10}+\frac{180318505670031407326392103326621091114968}{28965490966949451025539856545325}\cdot t^9-\frac{1563309030258537017739913535059990680274008}{28965490966949451025539856545325}\cdot t^8+\frac{8999985921255999882829175841094174391134656}{28965490966949451025539856545325}\cdot t^7-\frac{33897722050855347368126214831956096056815168}{28965490966949451025539856545325}\cdot t^6+\frac{81236044592807573674415276888895204199512192}{28965490966949451025539856545325}\cdot t^5-\frac{23750958446768270491099198505657376660911232}{5793098193389890205107971309065}\cdot t^4+\frac{19965686219241786564670122543474248843914752}{5793098193389890205107971309065}\cdot t^3-\frac{8867449593123421639701012205157426298714624}{5793098193389890205107971309065}\cdot t^2+\frac{1760607887430882388143028113180363993725952}{5793098193389890205107971309065}\cdot t-\frac{90450512222331736517370589764626744613888}{5793098193389890205107971309065}$
