An algebraic surface is defined as the set of points that satisfy a polynomial equation . The Picard number for an algebraic surface is a measure of the complexity of the curves on the surface. Algebraic surfaces with Picard numbers 1 to 45 are presented according to [1] and [2] containing parameters and .

More formally, the Picard number is the finite rank of the nonsingular complete variety of a sheaf cohomology group [3].
