What does "square of order 4n+2" mean here?
- tromp 5y agoA 4n+2 by 4n+2 square.
- dotancohen 5y agoThe term "order 4n+2" means a number of the form n (a positive integer) times four, then add two. So 6 fits (6 is 1 times 4, plus 2) and 10 fits (10 is 2 times 4, plus two) but 12 does not (twelve can not be made by multiplying a positive whole number by four, then adding two to that number). Thus a 6x6 square is permissible, as is a 10x10 square. But not a 12x12 square.
