If and only if R (A1, A2,..., am)

The n-dimensional sequence vectors A1, A2,..., am are linearly correlated,
It shows that there are people in the team who make up for the number,
And R (A1, A2,..., am) denotes the number of people who stand alone in a team

When m > N, any m n-dimensional vectors, A1, A2 , am must be linearly correlated

If they are linearly independent, then M is the basic vector dimension of M n-dimensional vectors. Then M = n is contradictory to the title
