If there was one less loyal lieutenant, though, we could have a tie here which would result in picking the default value. If the general ordered something other than the default value (e.g., default is retreat and the order was attack) the general will not be happy about this...

You may have figured out that since disloyal participants can lie at any step of the equation, we can't rely on their data at all. That's true! In the examples in the course we know that two participants are traitors and I've said they are L5 and L6. Therefore we could replace whatever they say with a question mark in the able rather than any particular answer, because they are liars. In real life though, \textit{some} message is received -- attack or retreat -- and it's only later we could identify which participants are the traitors.

Let's go back to the example of having eight participants: one general and seven lieutenants. So if we are lieutenant 1, we complete the table as below. The value for L1 is what we received from the general, but we get the remaining values from the other lieutenants.
