Dear all,

I want to determine a subset based on the indices of elements.

for example, I have a set i /0,4,3,1,5,2,6/ and the order of elements in this set is important to me. I want to define a subset that contains the third element of i to the sixth element. In more details, I want the subset to be as subi(i) /3,1,5,2/ but i do not want to type each element manually.
How should I define the mentioned subset based on the order of elements?

I appreciate it if someone can help me.
Thanks and regards,
Bahar

If you want it till the last or second from the last element you can use card(i) for comparison instead of 3 and 6.

Hope this helps.
