Now from looking to matrix we want (AB) (BC) (CD) .For symmetric reln (BA) (CB) (DC) should aslo be there. For transitivity (CA) (AC)(AD)(DA)(BD)(DB) will also come. So,total 16. 0 votes 0 votes Lakshman Bhaiya commented Jan 9, 2019 reply Follow Share Can you explain a bit more, I'm not able to understand$?$ 0 votes 0 votes raahul commented Jan 9, 2019 reply Follow Share According to matrix we want relation (AB) (BC) (CD). Now for satisfying symmetric we need(BA) (CB) (DC). Now we have (AB) (BC) we need (AC) and we have (BC) (CD) so ,we need (BD) for transitivity. Again we have to satisfy symmetric so,(CA) (DB). Just like this find all pairs for transitivity and make them symmetric also. 0 votes 0 votes Please log in or register to add a comment.
