Greetings all,

I have a question that says S is a bounded set of real numbers and that lub S and glb S are equal. The question wants to know what you can conclude about S (the set).

my understanding is that glb and lub are both unique numbers and therefore do not equal. The only thing I could think of is that S only contains one number like (0,0) or (5,5) but then I thought maybe in that case there is no glb lub

thanks
