%N Number of elements of rows of Golomb's sequence A001462, with one less 2, interpreted as triangle: Start with first row 1. The row sum of row n-1 gives the number of elements taken from A001642 (one less 2) of row n.
%C a(n+1) gives row sum of row n of this triangle.
%C Conjecture: a(n) for n>1 gives first differences of Lionel Levile's sequence A014644(n) for n>=3.
%C Conjecture: Final elements of the rows form A014644 except for duplicate 2.
%e The triangle begins 1; 2; 3,3; 4,4,4,5,5,5; ...
%e Row 4: [4,4,4,5,5,5] is generated from row 3: [3,3] because there are (3) 4's and (3) 5's in row 4.
