• Product of twin primes of form (4*k+1,4*k+3), k>0.at n=32A071697
• Numbers k equal prime(n)*prime(n+1) such that k+1 is a square and k-1 is even semiprime.at n=16A107423
• Semiprimes which are equal to product of two successive primes and also to sum of three successive primes.at n=25A133126
• Records in A166133.at n=23A256403
• Consider numbers n such that A166133(n) sets a new record and also satisfies A166133(n)=A166133(n-1)^2-1; sequence gives values of A166133(n).at n=8A256423
