Appears in sequences

• a(n) = floor( Gamma(n+5/7)/Gamma(5/7) ).at n=9A020075
• Start the sequence with a(1) = 3. From now on iterate: if |a(n)| is prime, subtract from a(n) the |a(n)|-th prime of the list of primes A000040 and if |a(n)| is nonprime, add to a(n) the |a(n)|-th nonprime of the list of nonprimes A018252.at n=22A374834
