  In [BN] the authors construct a special complex of degree 20 over M, which
for an open three dimensional set parametrizes smooth complex surfaces of
degree four invariant which are Heisenberg invariant and each member of the
family contains 32 lines but only 16 skew lines. The coordinates of the lines
however need not be real. For a point l in a Zariski open set of M an algorithm
is presented which evaluates the real coefficients of l in terms of the
K-coordinates of l. The author uses a code in Maple which allows him to
construct very explicite examples of real smooth Heisenberg invariant Kummer
surfaces containing the special configuration of 16 real skew lines. An example
is constructed at the end of the paper.
