cp's OEIS Frontend

This is a front-end for the Online Encyclopedia of Integer Sequences, made by Christian Perfect. The idea is to provide OEIS entries in non-ancient HTML, and then to think about how they're presented visually. The source code is on GitHub.

A060496 Each permutation in the list A060117 converted to Site Swap notation, with digits reversed. "Zero throws" (fixed elements) indicated with 0's.

Comments

This sequence is not well-defined for n >= 3628800 because the Site Swap notation can contain values exceeding 9, for example, the Site Swap notation for a(3628800) is [0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 10]. - Sean A. Irvine, Nov 25 2022

Crossrefs

Cf. factorial base representation A007623 and A060495, A006694.
In A060498 the digits are also "inverted", giving valid siteswap juggling patterns.

Programs

  • Maple
    SiteSwap2ToDec := proc(s) local i,z; z := 0; for i from nops(s) by -1 to 1 do z := 10*z + s[i]; od; RETURN(z); end;

Formula

a(n) = SiteSwap2ToDec(Perm2SiteSwap1(PermUnrank3R(n))).
