Centesimus Quinquagesimus

This is my 150th article here. I've officially run out of words!



Oh, alright then: Roman centurions were so called because they commanded a unit of 100 soldiers that marched in a 10x10 formation. Of course, this was on the way to battle. I'd like to know what the rules were for marching back with a lower number that doesn't have an integer (a whole number) for a square root.
