Operations with lists

Hello

 I have two questions.
The first:
How to remove from list repeating elements? For example is
list1 = (1 2 3 4 3 2 1) how to receive list2 = (4) having removed 1, 2 and 3
And how to receive list3 = (1 2 3 4) having removed only duplicating elements but not the initial.

The second:
How from two lists to receive one containing elements which is both in the first initial list and in the second? For example:
Is list1 = (1 2 3 4 5) and list2 = (2 4 6 7) how to receive list containing 2 and 4 as they is both in list1 and in list2?

 The case is certainly considered when the size of list is equal N

Best regard

    All many thanks for the help.

     To Lawrence ->I hope you can help to solve to me a problem with removal of repeating elements together with their duplicates. But even if it will not turn out, you have very much helped me, thanks.

    Best regards
