            Status: NEW
          Severity: trivial
          Priority: P5

           version:


The problem generates an error message for some seeds saying that the variables
are already defined.  I would guess that the issue occurs because the problem
attempts to redefine the variables when the determinant equals zero, since it
only happens for certain seeds and not all of them.

It still appears to work correctly and accept answers even in this case,
though.
