There are 4 that have 1 entry point from the C, and you can't use the middle C, because if you get there, there is nothing to go to: 4(1*1*3) makes 12 (you have to move diagonally away, then vertical, then you are at the middle and can go diagonally or horizontal, making 3 possibilities.)
Starting from the middle outside: 4(2 + 10 = 12) = 48.
Staring from the top and bottom center: 2(2 + 3 + 3 + 2 = 10) = 20.
I'm getting 80, but I feel like I did the last one wrong.
