OEIS Sequences

Write fundamental unit for real quadratic field of discriminant n as x + y*ω; sequence gives values of y for n == 3 mod 4. A53375

Let p = n-th prime of the form 4k+3, take the solution (x,y) to the Pellian equation x² - p·y² = 1 with·and smallest y >= 1; sequence gives value of y. A82394

The positive odd fundamental solutions y = y0(n) for the Pell equation x² - d·y² = +1. It turns out that d = d(n) coincides with A007970(n). A262026
