• Consider primes p such that integer part of the volume of cube with faces of area p is prime; sequence gives integer part of volumes.at n=31A107989
• Primes of the form (p^2-2)/7, where p is also a prime number.at n=20A165668
• a(n) is the smallest prime such that it and the previous three primes are all of the form x^2 + n * y^2.at n=13A212604
• a(n) is the number of 2 X 2 matrices with entries in {1, ..., n} that are not the product of two 2 X 2 positive integer matrices.at n=20A260550
