 The base case is for oriented manifolds, where we obtain no extra algebraic data.
 
 For 1-categories based on unoriented manifolds, 
-there is a map $*:c(\cX)^1\to c(\cX)^1$
+there is a map $\dagger:c(\cX)^1\to c(\cX)^1$
 coming from $\cX$ applied to an orientation-reversing homeomorphism (unique up to isotopy) 
 from $B^1$ to itself.
 Topological properties of this homeomorphism imply that 
-$a^{**} = a$ (* is order 2), * reverses domain and range, and $(ab)^* = b^*a^*$
-(* is an anti-automorphism).
+$a^{\dagger\dagger} = a$ ($\dagger$ is order 2), $\dagger$ reverses domain and range, and $(ab)^\dagger = b^\dagger a^\dagger$

 For 1-categories based on Spin manifolds,
 the the nontrivial spin homeomorphism from $B^1$ to itself which covers the identity
