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 A336800 The next prime, D, after 13 for which x^2-D*y^2=3 has a solution is 73 and the least positive y for which it has a solution is y=11, which is larger than 1, so it is a new record y value. So, 73 is a term of A336796 and 11 is a term of this sequence. %Y A336800 Cf. A033315, A336796. %K A336800 nonn %O A336800 1,2 %A A336800 _Christine Patterson_, Feb 04 2021
