Abstract： The low-lying states of a spin-aligned 6-electron quantum dot may prefer the regular hexagon and regular centered pentagon structures. However, these favourable structures may be prohibited by inherent symmetry. Based on this consideration, a couple of equations are deduced. The solution of these equations gives exactly the magic numbers of the 6-electron dot.
