Given A = {1, 2). List all the relations on A.

Explanation

To find all the relations on the set A = {1, 2}, we can follow these steps:

### Step 1: Understand the concept of relations
A relation on a set A is a subset of the Cartesian product A × A. The Cartesian product A × A consists of all possible ordered pairs (a, b) where a and b are elements of A.

### Step 2: Determine the elements of A × A
Given A = {1, 2}, we can find A × A:
- A × A = {(1, 1), (1, 2), (2, 1), (2, 2)}
