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).
EXAMPLE
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.
