Need to make sure to write a power of 4, and that if the number of elements, trim elements in the set?

If we are required us to write many Z power 4 we need to cut our set up of 4 elements? because in my case, the variety Z may consist of 7 elements
Z = {1,2,3,4,5,6,7}

Solution
Read the question carefully:

So you can easily take any 4-element set Z, and to work with them.

P. S. understanding the conditions of the problem is half of solving the problem, so I recommend to pay attention to every word any math problems.
And we also carry out various operations on an arbitrary subset as the same as the parent variety.
For example to know the number of elements in the subset, i.e. the capacity. - wilmer_Franecki commented on July 4th 19 at 23:32
? - wilmer_Franecki commented on July 4th 19 at 23:35
: a subset of set A is the set B all of whose elements belong to A.
So Yes, over the subset B can perform any operations valid to perform on sets. Power to learn - it is possible, in this case, you are asked to take a subset with a given capacity. You can even allocate a subset of a subset - if required. - heaven_Lang commented on July 4th 19 at 23:38
