I have written Maple code for the following topics:

• Elliptic stable envelopes of affine type A quiver varieties

• Wreath Macdonald polynomials

1. Here is a text file containing many wreath Macdonald polynomials. It can be read directly into Maple, or into another CAS after possible reformatting. The first index in the table is the partition and the second is the number of "colors". 

2. Here is a Maple worksheet (stored as a text file) that was used to produce the examples in the previous text file. Before reading it into a Maple worksheet, one must read in a (ideally large) library of Schur polynomials (in terms of power sums) and store it as the table "schur". For your convenience, here is one such library, stored as a text file.

• Reverse plane partitions over posets

• Vertex functions of zero-dimensional quiver varieties

• The Fock representation of the elliptic Hall algebra

I also have (less refined) code for many other topics that appear in my papers and may be willing to share upon request.
