Peter, I think I understand it differently.  Concrete example in GF(256) for k=6, m=4:

First, create a 3 by 6 cauchy matrix, using x_i = 2^-i, and y_i = 0 for i=0, and y_i = 2^i for other i.  In this case:   x = { 1, 142, 71, 173, 216, 108 }  y = { 0, 2, 4).  The cauchy matrix is:

Sorry, I took xi and yj to mean a constant x multiplied with i and a
constant y multiplied with j, rather than x_i and y_j.
