For a finite group G in GL(n), a G-equivariant coherent sheaf F is call a G-constellation if H^0(F) is isomorphic to the regular representation of G. On the other hand, for the subgroup G in GL(3,C) of type 1/r(1,a,r-a), the quotient C^3/G has a certain toric resolution of singularities, which is called the economic resolution. In this talk, we present a moduli interpretation of the resolution as a moduli space of G-constellations.
