There are several students who just form an eight-column rectangular matrix. If adding 120 people to the queue or subtracting 120 people from the queue can form a square square, how many students are there in the original square square?
有若干名学生，恰好组成一个八列长方形方阵．如果在队列中再增加120人或从队列中减去120人，都能组成一个方形方阵，那么原长方形方阵中有多少名学生呢？
