Effective construction of some Eckardt surfaces is given. In particular, not only their Picard number may be big but also an anticanonical divisor may have a very large number of irreducible components. Furthermore, the question about goodness position of the points over which these surfaces are built is handled.

Abstract
Effective construction of some Eckardt surfaces is given. In particular, not only their Picard number may be big but also an anticanonical divisor may have a very large number of irreducible components. Furthermore, the question about goodness position of the points over which these surfaces are built is handled.File in questo prodotto:
