The taxicab distance between points \left(x_{1}, y_{1}\right) and \left(x_{2}, y_{2}\right) in the coordinate plane is given by
\left|x_{1}-x_{2}\right|+\left|y_{1}-y_{2}\right|
For how many points P with integer coordinates is the taxicab distance between P and the origin less than or equal to 20 ?
