| Abstract: | The author abstracts the concept of compound map, the given definition of general compound map and general compound permutation, and discusses some propertiesof general compound map and the relation between it and map in usual sense. The author also gives definition of compound symmettric SA/R, discusses its structures and the relation be tween SA/R and compound symmetric group Sm. l, which is defined. |
