Did you mean to use the ring Zmod(2^(e*2))
(the integers modulo $2^{2e}$) instead of GF(2^(e*2))
(the finite field of order $2^{2e}$)? They are different things.

It can only be invertible in a ring where the determinant over $\mathbb{Z}$,
2^81 * 274177 * 67280421310721
is invertible, e.g. modulo primes which do not divide this number.
