• Variation of Boustrophedon transform applied to 1,1,1,1,... Fill an array by diagonals, in alternating directions. The first entry is 1 each time. For the next element of a diagonal, add to the previous element the elements of the row and the column the new element is in. The final element of each diagonal gives a(n).at n=7A059513
• The array described in A059513 read by antidiagonals in the 'up' direction.at n=35A059574
