Comments

A permutation of the natural numbers. Row 1 consists of those congruent to 1 mod 3. (One can then delete row 1 of A114883, leaving only numbers congruent to 0 or 2 mod 3 and then replace each by its rank, thus obtaining another permutation of the natural numbers.)

Also numbers from the array A083140, without the first row, minus 1 divided by 2.

Examples

			Start with the northwest corner of A114881:
  1  3  5  7   9
  2  8 14 20  26
  4 24 34 54  64
  6 48 76 90 118
Delete row 1, leaving all the even positive integers; divide them by 2:
  1  4  7 10 13
  2 12 17 27 32
  3 24 38 45 59
