%N Numbers k such that A354512(k) < omega(k); complement of A354525.
%C Numbers k such that there is a prime factor p of k such that gpf(k+p) != p.
%C Numbers k such that there is a prime factor p of k such that k+p is not p-smooth.

%e 57 is a term since the prime factors of 57 are 3,19, and we have gpf(57+3) != 3.
%o (PARI) gpf(n) = vecmax(factor(n)[, 1]);
%o isA354526(n) = my(f=factor(n)[, 1]); for(i=1, #f, if(gpf(n+f[i])!=f[i], return(1))); 0
