A368053 - cp's OEIS frontend

A368053 Array read by descending antidiagonals, where row n=0 lists the natural numbers. Each new row n=1,2,... is found by taking the number n in the previous row and "leaping" it over the next n terms to its right, while reversing the order of the skipped terms. (see example).
