Binary Relation

Let A = {1, 2,3} and B={1,2,3,4}, define a binary relation R from A to B as follows     
           R= {(a, b) E AxB | a b}
(i)    Find the order pairs in R.
(ii)    Find domain and range of R.
(iii)    Draw the Directed graph of R.
(iv) Make the matrix representation of R

Re: Binary Relation

I don't know about anyone else, but I can't see the character:

R= {(a, b) E AxB | a b}

Between a and b.
