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 61st year, we have over 378,000 sequences, and we’ve reached 11,000 citations (which often say “discovered thanks to the OEIS”).

%N An infinite audioactive word, one of four in the cycle that results from the limit of the 'Look and Say' sequence using method B with an initial term of 1.

%C Look and say once generates A120965, the second iteration generates A120966, the third gives A120967 and the fourth iteration returns to this sequence.

%Y Cf. A007651, A120965, A120966, A120967.
