A113676

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.

1, 1, 2, 6, 27, 234, 6202, 1084009, 4362192095 (list; graph; refs; listen; history; internal format)

	OFFSET	`1,3`
	COMMENTS	`a(n+1) gives row sum of row n of this triangle.` `Conjecture: a(n) for n>1 gives first differences of Lionel Levile's sequence A014644(n) for n>=3.` `Conjecture: Final elements of the rows form A014644 except for duplicate 2.`
	EXAMPLE	`The triangle begins 1; 2; 3,3; 4,4,4,5,5,5; ...` `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.`
