> Remove Duplicates From List, List Dup

Hello,

I am trying to find an easy way to remove duplicates from a list (probably a function that I can use over and over again).
So far I tried the following:
list (n1,n2,n3,n4,n2)
list2(n1, if(n2 <> n1, n2, ""), if (n3 <> n1 and n3 <> n2, n3,"")....).
I know there must be an easier way of doing this, specially for large lists.
On another note, is there a function that tells me how many items there are in a list, something like:
x = count(list1).

Thanks in advance.

I would create the list and use the isunique condition to assure that each item in the list is unique. For example:
a1 range(2,60)
a2 range(2,60)
a3 range(2,60)
a4 range(2,60)
a5 range(2,60)
a6 range(2,60)
a7 range(2,60)
a8 range(2,60)
condition isunique(a1,a2,a3,a4,a5,a6,a7,a8)
alist list(a1,a2,a3,a4,a5,a6,a7,a8)

You can then choose as many items from that list as you wish.
