In Exercises $8-10,$ write the relation $R,$ given by the matrix, as

a set of ordered pairs.

$,2([1,0,1,0],[0,1,1,1])$

How can we quickly determine whether a relation $R$ is

antisymmetric by examining the matrix of $R($relative to

some ordering$)?$

Tell whether the relation of Exercise $10$ is reflexive, sym$-$

metric, transitive, antisymmetric, a partial order, and$/$or an

equivalence relation.
