- The collection of all Suslin sets is closed under countable unions and countable intersection.
- Not all Suslin sets are Borel sets (in non-trivial metric spaces such as ).

Famous quotes containing the words properties of, properties and/or sets:
“The reason why men enter into society, is the preservation of their property; and the end why they choose and authorize a legislative, is, that there may be laws made, and rules set, as guards and fences to the properties of all the members of the society: to limit the power, and moderate the dominion, of every part and member of the society.”
