You would know if there is no more left to find as each magic v that adds up to the same amount will always have eight ways to put it as. The bottom number will always stay the same and the total of each arm n the magic v's like 5 4 adds up to 8 on each side with consecutive numbers just like 2 3 which has
2 3 5 4
1 1
just been mixed up from each arm. There is one thing that one has to remember with differently put out magic letters that are supposed to have equal totals is that the bottom number always has to stay the same or the total will be different. If you mix each number not including the bottom number of v you will find there are 8 different ways it can be put out.
I thoroughly believe this is the best website ever made for learning.
