Hey everyone,

New here but I'm a bit stuck. Ive looked around in list tools as well as tried but I havent had any luck.

Suppose I have a list defined as FirstList:=[A,B,C,D,E,F]. Now I want to create (and label) all possible
lists from FirstList which contain 4 elements which dont have an element repeated within the same list
In this example, there are 15 lists in total i.e.

Sublist[1]:=[A,B,C,D]:
Sublist[2]:=[A,B,C,E]:
Sublist[3]:=[A,B,C,F]:
Sublist[4]:=[A,C,D,E]:

..etc

Is there a simple way to do this???

Any help is appreciated!
