It isn't any 25000 character limit that is getting you:
you are trying to find the closed form solution to a polynomial
of order 12 that does not happen to be factorable down
to polynomials of degree 5 or less (degree 5 is the maximum
for which closed form polynomial solutions always exist.)
Using Maple directly, there is simply no closed form solution
available for cv12. Beyond cv3, even where the closed form
solutions exist in principle, Maple will just show a generalized
placeholder instead (closed form quadratics and quintics are
pretty messy at the best of times.)
