%N Irregular triangle read by rows in which the n-th row (n>1) lists distinct "factors" of n for the sieve described in A262775.
%C 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.

%H Max Barrentine, <a href="/A274568/a274568.txt">Rows n = 0..10000.</a>
%e 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.
%Y Cf. A262775, A027748, A264940, A272565.
