    Please help me construct a diagram

    * Let A be the family of all subsets A of the natural numbers N where A has the following properties: A is finite and the greatest common divisor of the elements of A is 1.

    _Order A by set inclusion, that is X precedes Y if X is a subset of Y, and let B be the subfamily of A which consists of the sets in (a) which belongs to A. Construct a diagram of B.

    Please think about this problem for ten minutes and then repost it in the Discrete Math subforum. I am asking you to think because it seems that you copy-pasted the problem from a PDF file into the forum without even thinking if what you posted makes sense. For example, in the phrase "Let A be the family of all subsets A," the two A's must be typeset in different fonts. And what about the essential part (a), which you omitted? Finally, please describe your difficulty in solving the problem.
