[seqfan] A019303 "Pascal sweep" for k=2: draw a horizontal line ...

[Georg.Fischer]

Hello Seqfans,

this sequence says nothing (Formula, comment, crossref.) but:

A019303 "Pascal sweep" for k=2: draw a horizontal line through the 1 at 
C(k,0) in Pascal's triangle; rotate this line and record the sum of the 
numbers on it (excluding the initial 1).		0
1, 4, 1, 5, 1, 6, 1, 7, 1, 8, 1, 9, 1, 10, 1, 11, 1, 12, 1, 13, 1, 14, 
1, 15, 1, 16, 1, 17, 1, 18, 1, 19, 1, 20, 1, 21, 1, 22, 1, 23, ...
OFFSET 0,2

It seems to be a subsequence of:

A179820		a(n) = n-th triangular number mod (n+2).		
0, 1, 3, 1, 4, 1, 5, 1, 6, 1, 7, 1,
OFFSET 0,3

I wonder whether I'm the only one who does not understand
the name of A019303. I googled "Pascal sweep" - I seems
not to be a common term.
