• Value of x corresponding to the minimal solution of the Pell equation x^2+d*y^2, as d runs through the squarefree numbers.at n=57A023677
• Numerators of continued fraction convergents to sqrt(94).at n=15A041168
• Numerators of continued fraction convergents to sqrt(376).at n=15A041712
• Numerators of continued fraction convergents to sqrt(846).at n=15A042632
• Write fundamental unit for real quadratic field of discriminant n as x + y*omega; sequence gives values of x for n == 2 mod 4.at n=19A053371
• a(n) is smallest natural number a satisfying Pell equation a^2 - d(n)*b^2= +1 or = -1, with d(n)=A000037(n) (a nonsquare). Corresponding smallest b(n)=A077233(n).at n=84A077232
• Positive fundamental solution x0 corresponding to the even y0 = 2*A261250 of the Pell equation x^2 - D y^2 = +1.at n=56A262024
• Take the solution to Pellian equation x^2 - 8*n*y^2 = 1 with smallest positive y and x >= 0; sequence gives a(n) = x, or 1 if n is twice a positive square. A368339 gives values of y.at n=46A368340
