Is there a standard symbol for this relation? Like isomorphism-subscript-c? —Preceding unsigned comment added by 128.100.216.124 (talk) 20:00, 27 April 2011 (UTC)[reply]

In the context of computability theory two sets

A;B\subseteq \mathbb {N}

which are recursively isomorphic are often denoted

A\equiv B

. But this may be confused with the symbol of the congruence relation on the set of integers. -- 86.56.98.28 (talk) 22:55, 28 May 2013 (UTC)[reply]
