[[1]],
[[0], [-1]],
[[0], [-1], [1]],
[[0], [-2, 1], [2], [-1]],
[[0], [-5, 5, -1], [5, -2], [-3], [1]],
[[0], [-14, 21, -3, -6, 1], [14, -12, 2], [-9, 3], [4], [-1]]],
[[0], [-42,84,-28,-28,7,7,-1],[42,-56,7,14,-2],[-28,21,-3],[14,-4],[-5],[1]]
Replacing the sublists by their sums reduces the triangle to a signed version of the triangle A097805. The column 1 of sublists is A111785 in a different order.
