• Hypotenuses of special Pythagorean triples constructed from twin primes as follows: {u, w}={p,p+2}; side a=2p(p+2), side b=(p+2)^2-p^2 and the terms of sequence are values of c=a(n)=p^2+(p+2)^2=phi(a/2)+1+sigma(a/2)+1.at n=16A063533
• Semiprimes that are sums of squares of two consecutive primes.at n=10A216432
• Numbers k such that the equation x^2 - k*y^4 = -1 has a solution for which |y| > 2.at n=38A356488
