%N A244228 The lengths of runs in A244225, the first differences of A244223.
%C A244228 The sequence gives the distances between successive 1-terms in A244221, i.e. the odd representations in Greedy Catalan Base (A014418, A244161).
%C A244228 a(56) = 4 is the first term larger than 3 in this sequence. Cf. the example section of A244226.

%F A244228 a(n) = 1 + A244227(n).
%e A244228 The first odd term in A014418 is A014418(1) = 1, and the second occurs at A014418(3) = 11, and the third at A014418(6) = 101, and the fourth at A014418(8) = 111, thus the first three terms of this sequence are (3-1) = 2, (6-3) = 3, (8-6) = 2.
