The system of the Kohn-Sham equations for two-dimensional electrons in the quantum dot with a large number of electrons (up to 140 electrons) is numerically solved. New series of magic numbers for the complete angular moment of electrons in the quantum dot in the high magnetic field are found. For low average density of electrons, it has been shown that two electrons are localized on an impurity and the electron density has peaks and troughs with a period $\approx \pi L$.
