# QuadricSurface -- type of HashTable

## Description

QuadricSurface is a type of HashTable storing information about a smooth quadric surface in P^3. The keys of a QuadricSurface are: IntersectionPairing, HyperplaneClass, CanonicalClass, Ideal.

## Methods that use an object of class QuadricSurface :

• "divisor(List,QuadricSurface)" -- see divisor -- creates a Divisor
• ideal(QuadricSurface) -- extracts the ideal of a surface
