• Fourth term of balanced prime quartets: p(m-2)-p(m-3) = p(m-1)-p(m-2) = p(m)-p(m-1).at n=32A054803
• Primes from merging of 5 successive digits in decimal expansion of exp(Pi).at n=19A105010
• Primes such that the outer 2 digits are n and n+1 and all inner digits are 4, where 0 < n < 9.at n=2A108821
