J. Mathar_, Feb 16 2021 %H A336796 Christine Patterson, <a href="/A336796/a336796.txt">COCALC (Sage) program</a> %e A336796 For D=13, the least positive y for which x^2-D*y^2=3 has a solution is 1. The next prime, D, for which x^2-D*y^2=3 has a solution is 61, but the smallest positive y in this case is also 1, which is equal to the previous record y. So, 61 is not a term. %e A336796 The next prime, D, after 61 for which x^2-D*y^2=3 has a solution is 73, and the least positive y for which it has a solution in this case is y=11, which is larger than 1, so it is a new record y value. So, 73 is a term in this sequence and 11 is a term in A336800. %Y A336796 Cf.
