Is there a build-in function that gets the cardinality
of the set? I was unable to find it in the
documentation.
Unfortunately the function card() is not implemented yet.
The equivalent expression sum{my_set}1 can be used instead.

Thanks for your reply. In the set, a dummy index plus
1 points to the next element. Is it cyclic? 1..5, j=5,
i=j+1, i=1?

No, it is not. You should write something like
i = if j 5 then j + 1 else 1
or more intricate
i = mod(j,5) + 1
