OEIS Sequences

Semiprimes that are sums of squares of two consecutive primes. A216432

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-p² and the terms of sequence are values of c=a(n)=p²+(p+2)²=φ(a/2)+1+σ(a/2)+1. A63533

a(n) = Min { m > n | prime factorizations of m and n differ in one factor only}, a(1) = 1. A64802
