In the lucid notation by G. Frege:

Well, actually, I used a slightly other notation.

For example *I* would write

But notation is not enough. The notation only expresses a certain
notion, in this case the notion of /limit/ for sequences of sets.

You first have to get a thorough understanding of the notion of /limit/
for sequences of sets before you can actually _use_ the notation in a
meaningful (or at least mathematically correct) way.
