EXAMPLES We let to the reader the verification of the following
assertions. Example 1 is a family of interval orders which is neither
row-homogeneous nor column-homogeneous. Example 2 is a
column-homogeneous family of interval orders which is not
row-homogeneous but where each interval order is a semiorder. Example 3
is an homogeneous family of interval orders which are not semiorders.
Example 4 is an homogeneous family of semi orders . . 8 __ --, b
