That said, we had plenty if 747s with 4 axle set up, and the odd DC10 with 3 although they are shorter than the 777 300 so probably less if an issue.
Some aircraft that have 4 sets of main undercarriage have the ability where some/all of the whole wheel "block" can turn so the aircraft can turn tighter corners. A bit like on some cars where the rear wheels turn the opposite direction to the front wheels.
Think the A380 has it, but I'm not sure if the 747 or DC10 did.
