%N Cumulative counting sequence: (adjective-before-noun) pairs with first term 1.
%C After starting with 1, successive segments are generated in adjective-before-noun pairs as in A217760, not as in A055187. That is, noun-integers occur in order of 1st appearance, not increasing order.

%e Writing pairs vertically, the initial segments are
%e 1..1..3..4 1..6 2 1..8 3 2 1 1..11 5 3 2 3 1
%e ...1..1..1 3..1 3 4..1 3 4 6 2...1 3 4 6 2 8.
%e The 5th segment is read "6 1's and 2 3's and 1 4," this being a count of all the previously written numbers. The numbers 6,2,1 are used as adjectives, whereas 1,3,4 are used as nouns. Here, the nouns are kept in order of first appearance; in A055187, they are in increasing order. - _Clark Kimberling_, Mar 25 2013
