%N Strings giving winning positions in Tchoukaillon (or Mancala) solitaire.

%C a(n) gives string listing winning position for n stones.

%C Sum of numbers in a(n) is equal to n.

%C Using the chromatic (tet-12) scale, (if C=0, 12, 24...) all integers correspond to pitches C, C#, G#, A, Bb, B, a recursive pattern that evenly bisects the octave and avoids the tritone (IC6). - _Nik Bizzell-Browning_, Apr 27 2019

%F To get the next term, if rightmost 0 is in position i, replace it by i and subtract 1 from all earlier entries.

%e For example, a(10) = 53111; rightmost 0 is in position 6, so get 653111 -> a(11) = 642000.
