when defining an empty set, set1:=set[ ] [↵] returns at the input (history) [up, up key + copy] %{ %} and at the output [up key + copy] %{ %}. These symbols are not very intuitive and ugly. Also to return using the symbols [] for three different types of data sets, vectors and polynomials is very confusing.

I propose that it be visualized set in the history with the following delimiter 【 】

and for another math objects

brackets/parentheses delimiters are displayed as () // ok

lists delimiters are displayed as { } // ok

vector delimiters are displayed as [ ] // ok

matrix delimiters are displayed as [ ] // ok

Polynomial delimiters are best shown as 〘 〙 instead of []

set delimiters delimiters are best shown as 【 】 instead of []

sequences delimiters are best shown as 〔 〕instead of ()

set1:= set[ "H", "E", "L", "L", "O"] [↵] returns 【 "H", "E", "L", "O" 】 // the multiplicity of L is eliminated // ok

Another symbols for brackets/parentheses
