• Primes p such that 2^j+p^j are primes for j=0,1,2,16.at n=2A094493
• Number of base 7 circular n-digit numbers with adjacent digits differing by 5 or less.at n=6A125370
• Number of binary strings of length n with no substrings equal to 0001 0101 or 1000.at n=17A164471
• a(1) = 2. For n>1, let s denote the binary string of a(n-1) with the leftmost 1 and following consecutive 0's removed. Then a(n) is the smallest prime not yet present whose binary representation begins with s.at n=47A262350
