%N a(n) = n for n < 6; a(6n) = a(n); if every 6th term (a(6), a(12), a(18),...) is deleted, this gives back the original sequence.
%C A self-generating sequence. This is the m=6 analog of the m=10 variant A126616. Sequence A117943 is the m=3 analog with all terms decreased by 1.
%F a(n) = a(n/6) if n==0 (mod 6); a(n) = a(n - floor(n/6)) otherwise.
