What do you mean by "stable under a countable sum"?

I was hoping that you could help define. I have an idear that its about a sequence of sets which \epsilon is defined upon, but I'm not sure.

Any idears ??

What? Where did you get this question? Exactly what did it say? What you said in the last post made no sense.
