| 31. | Equinumerous finite sets have the same number of elements.
 
  | 
 | 32. | Similarly, any surjection between two finite sets of the same cardinality is also an injection.
 
  | 
 | 33. | Boolean algebra is isomorphic to the Boolean algebra of all subsets of a finite set.
 
  | 
 | 34. | There exist numerous topologies on any given finite set.
 
  | 
 | 35. | There are numerous partial orders on a finite set.
 
  | 
 | 36. | Testing whether a finite set of propositional formulas has a stable model is disjunctive programs.
 
  | 
 | 37. | The Gamma Knife has a finite set of indications,
 
  | 
 | 38. | These conformal field theories have a finite set of conformal families which close under fusion.
 
  | 
 | 39. | Enumerative definitions are only possible for finite sets and only practical for relatively small sets.
 
  | 
 | 40. | Thus any finite set of primes can be extended to a larger finite set of primes.
