%N Numbers k such that the least term in the periodic part of the continued fraction for sqrt(k) is 34.
%C The continued fraction expansion of sqrt((k*m)^2+t*m) for m >= 1 where t divides 2*k has the form [k*m, 2*k/t, 2*k*m, 2*k/t, 2*k*m, ...]. Thus numbers of the form (17*m)^2 + m for m >= 1 are in the sequence. Are there any others? - _Chai Wah Wu_, Jun 18 2016
%C The term 375804 is not of the form (17*m)^2 + m. - _Chai Wah Wu_, Jun 19 2016
