Comments

Does the n-th row always contain n entries?

Do the rows always form an n term arithmetic progression?

Conjecture: the last value in each row is A051903(n).

Examples

			Table begins:
   0
   2,  1
   5,  3,  1
   5,  4,  3,  2
  17, 13,  9,  5,  1
   6,  5,  4,  3,  2, 1
  37, 31, 25, 19, 13, 7, 1
For example, when n = 5, x^17 + x^13 + x^9 + x^5 + x is a multiple of 5 for all integers x > 1.
