Hi all.
I wanted to know if there is a (simple) way to define infinite sets like:
A={y|y belongs to N and y>3}
and then ask in x belongs to A.

Also- If I have 2 groups: A={1,2,3} B={x,y}, Can I make the "cartesian group"? [I don't know the name in English]: AxB={<1,x>,<1,y>,<2,x>,<2,y>,<3,x>,<4,y>}

Thanks,
Guy.
