Magma Code

- Here you can find the Magma code to compute isomorphism classes of fractional ideals, conjugacy classes of integral matrices and the isomorphism classes of abelian varieties over a finite fields.
- In the .zip file there are the .m files containing the code and two .txt files with examples showing what can you do with the code.
- Magma code (.zip)
- Don't hesitate to contact me if you have questions and/or comments!
