COMMENTS

The first 20 terms are identical to those given in Table 4.5, "The set of values m satisfying l(3m)<l(m)" on page 61 of Daniel Bleichenbachers PhD Thesis (see A104699). Only 109227 is not in Table 4.5.

The first 82 terms are identical to those of A104699, but A104699(83)=699051, for which A003313(3*699051)=22, is not in the current sequence, because A003313(6*699051)=23 < A003313(699051)=24. - Hugo Pfoertner, Dec 19 2015
