Abstract: This paper is devoted to obtaining estimates of the deviation of a parallelepipedal grid, which is a rational grid approximating the algebraic grid of a quadratic field.
New tasks have been set for further research.

Keywords: quadratic fields, approximation of algebraic grids, quality function, generalized parallelepipedal grid, Bykovsky set, Bykovsky sum, local lattice minima, minimal comparison solutions.
