Just to add here, as good a place as any:

 difference { //primary object first
  MainObject
  SecondaryObject
  SecondaryObject
  SecondaryObject
 }

 intersection { //primary object last
  SecondaryObject
  SecondaryObject
  SecondaryObject
  MainObject
 }

 merge { //any order(?) this one I'm not positive of at the moment
  SecondaryObject
  MainObject
  SecondaryObject
  SecondaryObject
 }

 union { //any order
  SecondaryObject
  SecondaryObject
  MainObject
  SecondaryObject
 }
