3) (a.3) for each relation, indicate whether the relation is a partial order, a strict order, or neither. if the relation is a partial or strict order, indicate whether the relation is also a total order. a) the domain is the set of all cell phone towers in a network. two towers can communicate if they are within a distance of three miles from each other. tower x is related to tower y if x can send information to y through a path of communication links. you can assume that there are at least two towers that are within three miles of each other. b) the domain is the set of all words in the english language (as defined by, say, webster's dictionary). word x is related to word y if x appears before y in alphabetical order. assume that each word appears exactly once in the dictionary. c) the domain is all subsets of set a (you do not need to know its specific definition for this problem). set x is related to set y if x is a subset of y.
