• Expansion of (x-x^3)/(1-3*x+2*x^2-3*x^3+x^4).at n=14A140824
• Number of nontrivial solutions (x,y,z) for each prime number p of the Fermat equation x^p + y^p + z^p = 0 mod (n) where n is prime of the form n = 2p + 1, and x, y, z are integers such that x < = y.at n=19A172426
• Consider the non-unitary aliquot parts, in ascending order, of a composite number. Take their sum and repeat the process deleting the minimum number and adding the previous sum. The sequence lists the numbers that after some iterations reach a sum equal to themselves.at n=15A307859
