**Problem 3:**
Given the following *Hasse diagram*:
**Tasks:**
a. Find the **maximal** elements.
b. Find the **minimal** elements.
c. Find a pair of **comparable** elements.
d. Find a pair of **incomparable** elements.
**Diagram Description:**
The diagram represents a partially ordered set using circles labeled as nodes "a," "b," "c," "d," and "e." Lines between these nodes indicate the order relationships:
- Node "a" is the lowest element connected upwards to both "b" and "c."
- Node "b" is connected vertically above "a" and horizontally to "d."
- Node "c" is connected above "a" and also horizontally to "d."
- Node "d" is connected above both "b" and "c."
- Node "e" is the highest element connected vertically to "b."
Interpretations of the relationships provide insights into the hierarchy and ordering of the elements.
