The work is devoted to the study of Diophantine equation $x^2-y^2(p^{2}-4q)=4t$, where $p=l+u(k^2-1)(l(k^2-1)-2k)$, $q=u(lk^3-2k^2-kl+1)+km+1$, $l=k+m(k^{2}-1)$, numbers $k,m,u$ are nonnegative integers, number $k$ is odd, and the right hand side $4t$ of the equation is sufficiently small positive integer. We give a complete description of solutions of the Diophantine equation.
Mots-clés : diophantine equation, integer solutions, diophantine approximations.
Keywords: generalized Pell's equation, quadratic fields, unit group
