| At the beginning I thought you mean a, b, c, d to be fixed numbers. I'm still not sure, but now I think you mean this set:
S := { (oo,b) | b in RR }
cup { [a, b) | a, b in RR }
cup { [a,oo) | a in RR }
cup { emptyset }
Now A is generated from S by building finite unions.. right? Ok, I'll think about that. Thanks!
