• a(n) = ((5^n mod 4^n) mod 3^n) mod 2^n.at n=15A064854
• Consider the mapping f(a/b) = (a^2 +b^2)/(a+b). Taking a =1, b = 2 to start with and carrying out this mapping repeatedly on each new (reduced) rational number gives the following sequence 1/2,5/3,17/4,305/21,... Sequence contains the numerators.at n=4A081479
• 9*n analog to Keith numbers.at n=17A282764
