In particular, find a list with the fewest number of different values with all four integers distinct, a list with the fewest number of different values with not all distinct, and a list with the largest number of different values. Include an explanation for why you think you have found the minimums and maximums.

**b)** Use various lists of four (not necessarily distinct) integers, a,b,c,d to see how many different values can be obtained for various groupings of a÷b÷c÷d.

Find the same lists as above.

**My Concerns:**

I am having a notation problem. What is meant by the a - b - c - d and the a÷b÷c÷d in this problem? I think if I knew what this meant I could answer the problem. Thank you.
