• Least a(n) such that the period of continued fraction for sqrt(a(n)) has at least n successive 1's.at n=16A060215
• a(n) is the least m such that a period of the continued fraction expansion of sqrt(m) is 1,1,1,...,1,1,1,Z and there are n ones in the period (Z is 2*floor(sqrt(m))). If no such m exists, a(n) = 0.at n=15A071296
• a(n) is the least k such that the denominators of continued fraction convergents for sqrt(k) match the first n Fibonacci numbers.at n=16A309666
