• Numbers n such that A078142(n) = A078142(n+1) = A078142(n+2), where A078142(n) is the sum of the differences of the distinct prime factors p of n and the next square larger than p.at n=14A073938
• a(n+1) = m + Sum_{j=0..n} (a(j)*a(n-j) + k) for n>=1, with a(0)=1, a(1)=5, k=1 and m=1.at n=7A176648
• Number of length n 1..(2+1) arrays with every leading partial sum divisible by 2, 3 or 5.at n=14A254821
• Take a squarefree semiprime and take the difference of its prime factors. If it is a squarefree semiprime repeat the process. Sequence lists the squarefree semiprimes that generate other squarefree semiprimes only in the first k steps of this process. Case k = 5.at n=16A296812
