For $n$ dimensions, $n+1$ reference points are sufficient to fully define a reference frame. I just want the above line explanation.
In a frame of reference, can we have one reference point or more than one?

It means you need to fix a point as the origin and then you need $n$ unit vectors for an $n$-dimensional frame of reference. If we consider the tips of the unit vectors and the origin as reference points then we need $\left(n+1\right)$ reference points to define the frame of reference. All the other points in the frame of reference can be written as a linear combination of the unit vectors.
