Or, look at the formations.txt file in the B5 Mod. I collected all of the mentioned formations, plus many more. Or, you could d/l it right here:
Formations.txt.
The biggest problem with formations is that they have a hard code limit of 31 ships. I am currently working on expanding all of the formations in that file to have as close to 31 ships, while still maintaining the original intent of the design. Anybody who cares about formations should send a request to Aaron (Malfador) for better ones in the standard game and for a huge increase in the available slots in each formation.
And yes, most experienced players have their ships break formation. However, the formation that you select for your fleet determines where the ships in the fleet start. Having a large portion of your ships scattered around behind the main front can be devastating to your fleet in a large battle.
