## Properties of binary relations - RST and RAT

Binary relations r, s, t, a
properties and drawing graphically.
Partioning a set with a binary relation that has the 3 properties:
r and s and t means we have
an equivalence relation.

How Partitions are related to
EQUIVALENCE RELATIONS. RST binary relations. Blocks, equivalence
classes.

Partially Ordered Sets,
aka POSETs are reflexive and antisymmetric and transitive.
