No, it is rather an example of the limitations of simple UTF-8 text, in
which the transpose superscript was too difficult to write. This has
nothing to do with FATT. Rather, the equations deliberatly (mis)quoted
are a best effort to list the essential algebraic ingredients from which
a sufficiently knowledgeable reader may be able to determine whether the
common `m` can or cannot be recovered from the various equalities.
