Error, (in LinearAlgebra:-Modular:-IntegerLinearSolve) invalid arguments to iratrecon

I ran a procedure that uses only `solve/linear`. The above error was returned. Any ideas how to prevent it or why it happened?

How does `solve/linear` reach LinearAlgebra:-Modular:-IntegerLinearSolve?

I have two lists. I would like to confirm that one is a permutation of the other. Which Maple procedure does this?

Edit:
So surprising answer is Maple has no builtin one command to establish the fact.

When using FunctionAdvisor(branch_cuts, f(x), plot="2D"); how do I enforce discontinuous lines be presented with option discont=true?

Does this happen to you (ChatGPT session):

How do I explain this:

isolve({a*b=4,a>=1,b>=1});
