Row 1 consists of Fibonacci numbers. To obtain T from the array T' in A094607, add 1 to every number in T', then shift row 1 one place to the right and fill the initial place with 1. %H A094608 <a href="/index/Per#IntegerPermutation">Index entries for sequences that are permutations of the natural numbers</a> %e A094608 A northwest corner of T: %e A094608 1 2 3 5 8 %e A094608 4 6 7 10 11 %e A094608 9 12 14 15 19 %e A094608 17 22 27 28 33 %Y A094608 Cf.
