There is no one on the left, which means Xiaoxiao's column is the last one, and she is the last one; There is no one behind, which means Xiaoxiao is the last line of her line, and she is the last person.

So this team has: 8×8=64 (people).

In fact, the concept of nobody on the left is the same as that of nobody on the right; Because our current reading habit is from left to right, we just don't react at once; This is also one of the key points of this exam (don't be bound by fixed thinking).

Note: the square team is a square formation, which can be square or rectangular; When the number of columns = the number of rows, it is square; When the number of columns ≠ rows is rectangular.
