A $1\times2\times3$ block is placed on an $8\times8$ board, as shown with the $1\times2$ face $X$ at the bottom.

It is rolled over an edge, without slipping, onto a $1\times3$ face $Y$, then onto the $2\times3$ face $Z$, then onto $X$, $Y$, $Z$ again in that order.

How many different squares on the board has the block occupied altogether, including the starting and ending positions?
