 We want to find 2-simplices which fill in this cycle.
 Choose a decomposition $M$ which has common refinements with each of 
 $K$, $KL$, $L$, $K'L$, $K'$, $K'L'$, $L'$ and $KL'$.
-(We also also require that $KLM$ antirefines to $KM$, etc.)
+(We also require that $KLM$ antirefines to $KM$, etc.)
 Then we have 2-simplices, as shown in Figure \ref{zzz5}, which do the trick.
 (Each small triangle in Figure \ref{zzz5} can be filled with a 2-simplex.)
