Descaminhos
"Descaminho" is most commonly used in an emotional sense, rather than to mean a physical path as is the case here:
___
A seguir você utilizará as tabelas para construir os caminhos e descaminhos para o grupo.
You can use the following tables to build the paths and (___) for the group.
___
I'm inclined to create a neologism for it; "errs", making a noun of the verb "to err", but I'm looking for suggestions before I resort to that.
