Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 56th year, we are closing in on 350,000 sequences, and we’ve crossed 9,700 citations (which often say “discovered thanks to the OEIS”).

%H <a href="/index/To#Hanoi">Index entries for sequences related to Towers of Hanoi</a>

%e Start by moving first disk from peg 0 to peg 1, second disk from peg 0 to peg 2, first disk from peg 1 to peg 2, etc. so sequence starts 0,1,1,0,...

%Y Cf. A060573 (smallest on peg 0), A060575 (smallest on peg 2), A055662 (whole configuration).

%Y Cf. A001511, A060571, A060572.
