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.
