4.1.1.2 Isomorphism Declarations

  ISO-DECL         ::= iso-decl SORT+

An isomorphism declaration ISO-DECL is written:

S1=...=Sn

It declares all the sorts S1, ..., Sn, as well as their embeddings as subsorts of each other. Thus the carriers for the sorts Si are required to be isomorphic. The Si must be distinct.
