Can you provide details of how you created the polyhedron? As David said,
Q.vertices() should make a copy before returning the result, and I would
like to recreate this so I can fix it.

Thank you David. Using deepcopy seems to solve the issue if I make a
separate copy after the call. But as you mentioned, the return of function
should be a copy object.

I think I found out.
There is an assertion in `tensor_constructor` which is too strict, and
`plethysm` should return an element of the parent, not of the tensor
product. I'll open a ticket.

Dear all,
On gitlab CI, I encountered a weird problem with the tarball
sage-8.7-Ubuntu_18.04-i686.tar.bz2
downloaded from the mirror. The first time sage is launched it
patches sources and fails with
/builds/videlec/surface_dynamics/SageMath/build/bin/sage-python23: line
31: /builds/videlec

Hello,
If you already have working code for this, the answer Erik recently gave
to a similar question (about Turing machines) may be relevant. I paste
it below:

I don't know, but perhaps

You probably want deepcopy. That being said, Q.vertices should probably
also make a copy before returning the result.
