%C A186355 Does this differ (apart from the additional 1) from A089108? - R. J. Mathar, Feb 25 2011
%e A186355 First, write
%e A186355 ...3..6..9....12..15..18..21..24.. (3*i)
%e A186355 1..3..6....10.....15......21.... (triangular)
%e A186355 Then replace each number by its rank, where ties are settled by ranking 3i before the triangular:
%e A186355 a=(2,4,6,8,9,11,12,14,15,17,....)=A186354
%e A186355 b=(1,3,5,7,10,13,16,20,24,28,...)=A186355.
