Conglomerate in mathematical literature. I rememeber I downloaded a pdf in category theory and after talking about classes it defined something called conglomerates, but I can't remember what that is and wikipedia has no article on it. 

If I remember correctly it brought up some kind of paradox and had to introduce conglomerates to solve it. My question is also if there exists a similar paradox that applies to conglomerates and creates even another object. Regards ;)

There are two wonderful resources:
