 A141045 Triangle of subsequences of A140825 with a mirror symmetry. 2
 -1, 1, -1, -19, 11, -19, 27, -11, 11, -27, -863, 271, -191, 271, -863, 1375, -351, 191, -191, 351, -1375, -33953, 7297, -3233, 2497, -3233, 7297, -33953 (list; table; graph; refs; listen; history; text; internal format)
 OFFSET 0,4 COMMENTS The triangle shows A140825(3) in the first row and fills the n-th 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 mirror-operation at the row centers. We are essentially reading numerators down columns of the triangle in A140825, a(i,j), 0<=i<=j-2. LINKS EXAMPLE The triangle starts: -1; 1, -1; -19, 11, -19; 27, -11, 11, -27; CROSSREFS Sequence in context: A050276 A107808 A214422 * A157411 A166525 A083156 Adjacent sequences:  A141042 A141043 A141044 * A141046 A141047 A141048 KEYWORD sign,tabl,less AUTHOR Paul Curtz, Jul 31 2008 EXTENSIONS Edited by R.
