Whereas in iii you require only 3 instances of relation. So this one is possible. 0 votes 0 votes arch commented Nov 22, 2017 reply Follow Share why not second possible? cycle also like triangle. 0 votes 0 votes joshi_nitish commented Nov 22, 2017 reply Follow Share but in 2nd you dont know length of cycle, as in triangle you know length =3 0 votes 0 votes Please log in or register to add a comment.
