Let S = {0,1,2,3,4,5,6,7,8}. Test the following binary relation
on S for reflexivity, symmetry, antisymmetry, and transitivity. xρy
if and only if x+y = 8.
Is ρ an equivalence relation?
If we change the relation to x ρ y if and only if x+y 6 8 how
will the cardinality of ρ change? Give a detailed explanation.
