ANSWER:-
Symmetric and reflexive but not transitive:
R={(a,a),(a,b),(b,a),(b,b),(c,c),(b,c),(c,b)}.
It is clearly not transitive
since (a,b)∈R and (b,c)∈R whilst (a,c)∉R.
it is reflexive since (x,x)∈R for all cases of x:x=a, x=b, and x=c Likewise, it is symmetric since (a,b)∈R and (b,a)∈Rand (b,c)∈R and (c,b)∈R

Python 3 Discrete Mathematics We are going to write a program to read in relations, show the matrix of the relation. We will also show if the relation is reflexive, symmetric, anti-symmetric and transitive. This program will read in files that the user gives. Normal Error handling applies.
