No. Store the polynomial as a string, it would be much more simple... and much more readable. At some point you might want to access the database without having to guess what is the data inside. The upstream database is only a text file? Do you know how they do in Snappy? There is a huge collection of 3 manifolds inside. It would be cool to have something somehow compatible.
