Mathematical Groups

Hello everyone,

I am trying to render my own definition of what a mathematical group is; in doing so, I have run into an ambiguity. Here is what I have thus far:

"A group is simply a set of objects * associated with some binary operator which acts on a pair of elements in G..."

I have used to a star to mark the place at which, I feel, ambiguity arises. The way it is written, the sentence seems to say that the binary operator is associated with the elements, and not with the set G as a whole. I would like to say that the binary operator is associated with the set as a whole. Would this wording seem to work better:

"A group G is simply a set of objects that is associated with some binary operator...."

I don't see the ambiguity at ( *) since "binary operator" is qualified by "acting on a pair" The ambiguity is "a" which, to me, means, it can act on one pair of objects, not necessarily any pair-wise combination in the set.
