Draw a Hasse diagram for a partially ordered set that has two maximal elements ad two minimal elements and is such that each element is comparable to exactly two other elements.

To draw:

A Hasse diagram for a partially ordered set having two maximal elements and two minimal elements whereas each element is comparable to exactly two other elements.

Given information:

Let S={a,b,c,d} be a partially ordered set.

Concept used:

Hasse Diagram: It is a mathematical diagram representing a partially ordered set with finite number or members involving transitive reduction.

Calculation:

Let S={a,b,c,d} be a partially ordered set, wherea
