#  Discussion:
#
#    A "distance" matrix for 11 objects.  The distance matrix must
#    be symmetric, contain nonnegative values, and have a zero 
#    distance from an object to itself.  However, we do not require
#    that the distances be geometrically realizable or meaningful.
#
#    In this example, each of the numbers between 1 and 55 shows up
#    as a distance between one pair of distinct objects.
