# Points in the tetrahedron

There is a regular tetrahedron with edge ledge of $2$ units. Your task is to put as many points within the volume occupied by the tetrahedron.

But there is a condition: there has to be at least $1$ unit distance between each points.

What is the maximum number of points you can put within the tetrahedron with the condition above?

Note that edges and vertices of tetrahedron are considered within the volume.
