Erratum to "Adding inverses to diagrams encoding algebraic structures"
and "Adding inverses to diagrams II: Invertible homotopy theories are
spaces"
Julia E. Bergner
In this note, we correct an error in one of our approaches to encode a
group structure by a diagram. We show that we instead obtain the
structure of a monoid with involution.
