There exists a linear transformation f which sends e 1 to e 2, and sends e 2 to e 1, and which is the identity on all other basis vectors. It can be checked that f(f(x)) = x for all x in V. That is, f is an involution of V. For a specific basis, any linear operator can be represented by a matrix T.
