COMMENTS
This sequence is analogous to the prime factors of n, but for the sifted set A262775. If n is equivalent to some term A262775(k) mod A262775(k+1), then row n will include the term A262775(k+1). Row 1 is zero.

EXAMPLE
Row 2 is 2,3 because 2==0 mod 2 and A262775(0)=0, A262775(1)=2, and 2==2 mod 3 and A262775(1)=2, A262775(2)=3.
