There is no multiple attack action nor is there a limit on using the extra attack except it must be on the fighter's turn. You get the extra attack whenever take an attack action, and with action surge you gain a second action which allows you to take a second attack action and all that entails.
Okay, 2048 attacks it is. Can anyone beat that?
This is also another reason not to go with that ruling on Action Surges, but hey...if we are going to abuse the system...here we go.
