How do I ask PAUP* to examine every possible tree topology?
Here’s how to do this, but keep in mind that the number of possible unrooted bifurcating tree topologies increases factorially with the number of taxa. This means that for even a 14 taxon problem, it will take PAUP* several centuries to complete this analysis! It probably is not a good idea to try this command if you have more than ten taxa currently included.
