Primes of the form n³-6. A201310

a(1) = 2; for n > 1 if n is even a(n) = gpf(1 + ∏_{odd m,m<n}a(m)), while if n is odd a(n) = gpf(1 + ∏_{even m,m<n}a(m)). A258581

a(1)=5; thereafter a(2n) = nextprime(a(2n-1)²), a(2n+1) = nextprime(floor(2·a(2n)/(a(2n-1) + 1))) where nextprime(.) is A007918(.). A181616
