COMMENTS

The triangle shows A140825(3) in the first row and fills the nth row by successively skipping two terms of A140825 and taking the next n terms. The absolute values of the triangle generated this way are symmetric with respect to mirroroperation at the row centers. We are essentially reading numerators down columns of the triangle in A140825, a(i,j), 0<=i<=j2.
