%S 3,0,14,218,164,7316138,42678240

%N Least m such that the maximal palindrome within the period of the continued fraction for sqrt(m) is the n-th row of Pascal's triangle; or 0 if no such number exists.

%C A056825 is a similar sequence based on the same maximal palindrome.

%e For n=3, continued fraction for sqrt(218) is [[14],[1,3,3,1,28]]. Maximal palindrome in period -> (1,3,3,1) is the 3rd row of Pascal's triangle.

%Y Cf. A003285, A007318.
