Isopermutation Group.

The concept of 'Isotopy' as formulated by Ruggero Maria Santilli plays a vital role in the development of Iso mathematics. Santilli defined iso-fields of characteristic zero. In this paper we extend this definition to define Iso-Galois fields which are essentially of non-zero characteristic. Isotopically isomorphic realizations of a group define isopermutation group which gives a clear cut distinction between automorphic groups and isotopic groups. [ABSTRACT FROM AUTHOR]
