Appears in sequences

• Composite-then-prime recurrence; a(2n) = a(2n-1)-th composite and a(2n+1) = a(2n)-th prime and a(1) = 1.at n=12A064961
• Primes p such that the differences between the 5 consecutive primes starting with p are (2,6,6,6).at n=16A078951
• Slowest increasing sequence of odd primes such that the partial sums of the sequence from the second on are perfect powers.at n=14A174722
