This package consists almost entirely of example code for the main text and exercises of the book ’3264 & All That: Intersection Theory in Algebraic Geometry’ by Eisenbud and Harris. Most of the example code relies on the package Schubert2. The information in this package is best accessed via the help or viewHelp commands.

Conventions in effect throughout:

-Blackboard bold is represented in code by doubling a letter, so for example `G(2,4)` and `GG(1,3)` are both the Grassmannian of lines in *ℙ ^{3}*.
