• "BGJ" (reversible, element, labeled) transform of 1,0,1,0... (odds).at n=13A032050
• Bidirectional 'Delannoy' variation of the Boustrophedon transform applied to all 1's sequence: Fill an triangular array in alternating directions. Let the first element of each row in that direction be equal to 1. Each next entry is given by T(n,k) = T(n,k +/- 1) + T(n-1,k-1) + T(n-1,k) + T(n-2,k-1), where the +/- depends on which is the previous element in the direction one is filling in the row. The final number of row n gives a(n).at n=7A064643
• Array defined in A064643 read from left to right (cf. A107783).at n=28A064644
• Array defined in A064643 read in direction in which it was created.at n=35A107783
• Number of (n+2)X(4+2) 0..1 arrays with every 3X3 subblock sum of the two sums of the diagonal and antidiagonal minus the two minimums of the central column and central row nondecreasing horizontally, vertically and ne-to-sw antidiagonally.at n=21A254903
• Partial sums of the number of active (ON, black) cells in n-th stage of growth of two-dimensional cellular automaton defined by "Rule 33", based on the 5-celled von Neumann neighborhood.at n=40A269812
• Sum of the second largest parts in the partitions of n into 6 parts.at n=46A308872
