I was wondering, is S a subset of S-bar its closure? For example, if p belongs to S, does p belong to S-bar too? Does it go the other way, S-bar is a subset of S?(adsbygoogle = window.adsbygoogle || []).push({});

If it is true that S is a subset of S-bar does this automatically mean that S is closed?

Thanks
