Returns a set theoretic intersection of X and Y (X and Y are vectors pretending to be sets).

- IsIn
IsIn (x,X)

Returns

`true`

if the element x is in the set X (where X is a vector pretending to be a set).- IsSubset
IsSubset (X, Y)

Returns

`true`

if X is a subset of Y (X and Y are vectors pretending to be sets).- MakeSet
MakeSet (X)

Returns a vector where every element of X appears only once.

- SetMinus
SetMinus (X,Y)

Returns a set theoretic difference X-Y (X and Y are vectors pretending to be sets).

- Union
Union (X,Y)

Returns a set theoretic union of X and Y (X and Y are vectors pretending to be sets).
