  The concept of fractional charge is central to the theory of the fractional
quantum Hall effect (FQHE). Here I use exact diagonalization as well as
configuration space renormalization (CSR) to study finite clusters which are
large enough to contain two independent edges. I analyze the conditions of
resonant tunneling between the two edges. The "computer experiment" reveals a
periodic sequence of resonant tunneling events consistent with the
experimentally observed fractional quantization of electric charge in units of
e/3 and e/5.
