Arithmat

Giovanni Paolini and I have developed arithmat: a SageMath package to have fun with arithmetic matroids and integer matrices. It can be downloaded from GitHub or PyPI.

Characteristic OT

I developed some SageMath code to double-check the main results in The Frobenius characteristic of the Orlik-Terao algebra of type A by using symmetric functions. The code is available here in my GitHub profile .
