can we have 4 points is space that are all equidistant from one another? if yes how will you place them?

• If we consider 3-D space then it is possible.Just consider a pyramid with all its faces equilateral triangles.All the vertices are equidistant from each other.
  
  Moreover,if we are to place 4 points on a plane with the points being equidistant,then is is not possible.
