### 2.36.1 Definition : `set[]`

To define a set of elements, put the elements separated by a comma, with
`%{ ... %}` or `set[ ... ]` as delimiters.

Input :

`%{1,2,3,4%}`

`set[1,2,3,4]`

In the `Xcas` answers, the set delimiters are displayed
as and in order
not to confuse sets with lists.
For example, 1,2,3 is the set `%{1,2,3%}`,
unlike [1,2,3] (normal brackets) which is the list `[1,2,3]`.

Input :

`A:=%{1,2,3,4%}` or `A:=set[1,2,3,4]`

Output :

`1,2,3,4 `

Input :

`B:=%{5,5,6,3,4%}` or `B:=set[5,5,6,3,4]`

Output :

`5,6,3,4 `

**Remark**

The order in a set is not significant and
the elements in a set are all distincts. If you input
`B:=%{5,5,6,3,4%}` and `C:=%{3,4,5,3,6%}`, then
`B==C` will return `1`.
