  SUMMARY = {Inaccessible, strongly inaccessible and measurable cardinals
  are defined,
  and it is proved that a measurable cardinal is strongly inaccessible. Filters
  on sets are defined, some facts related to the section about cardinals
  are proved. Existence of the Ulam matrix on non-limit cardinals is proved.}}
