The total no. of reflexive relations on a set A having n elements is 2^n(n-1).Thus, the required no. is 2^20 = 1 048 576
A set relation refers to a relationship between two sets that describes how the elements of one set relate to the elements of another. Common types of set relations include subset, superset, disjoint, and intersection. For example, if set A is a subset of set B, every element of A is also an element of B. Set relations are fundamental in mathematics and are used to analyze and compare different sets and their properties.
The components of the relational model include tables (relations) to store data, columns to represent attributes, rows to represent records, keys to uniquely identify rows, and relationships to establish connections between tables.

A function is a mapping from one set to another such that each element of the first set (the domain) is mapped to one element of the second set (the range).
