When the article says:

A^n is isomorphic to B^n

should this be

is isomorphic to ,

or is this a special notation I don't know about?

Missed this, sorry... fixed. Dysprosia 09:02, 9 Aug 2003 (UTC)

something about p-ranks? (rank of an abelian group is the non-torsion rank plus sum of p-ranks for every prime p).

More Examples[edit]

How about explicit examples of abelian groups of rank greater than 1? Kerry (talk) 22:54, 22 September 2013 (UTC)Reply[reply]
