COMMENTS
A different sequence with the same definition is 1, 2, 3, 2, 3, 4, 3, 4, 5, 4, 5, 4, 5, 6, 5, 6, 5, 6, 7, 6, 7, 6, 7, 6, 7, 8, 7, 8, 7, 8, 7, 8, 9, 8, 9, 8, 9, 8, 9, 8, 9, 10, .. This would follow a more regular construction principle, that is, placing low numbers as early as possible: here a(7)=4 instead of a(7)=5 etc. - R. J. Mathar, Sep 25 2006
