• Number of strings of numbers x(i=1..n) in 0..2 with sum i*x(i)^4 equal to n*16.at n=17A184841
• Sequence a(n) = 3 + 5*A001519(n+1) appearing in a certain three circle touching problem, together with A246638.at n=10A246639
• a(1) = 13; for n > 1, if a(n-1) is even, then a(n) = a(n-1)/2; otherwise, a(n) = a(n-1) + prime(a(n-1)).at n=23A358166
