# A geometry problem by Satvik Choudhary

Geometry Level 3

As shown in the diagram, points $P_{I} , P_{2} , .., P_{I0}$ are either the vertices or the midpoints of the edges of a tetrahedron respectively. Then there are groups of four points$(P_{I} , P_{i} , P_{j} , P_{k})$ $(1 < i < j < K < 10)$ on the same plane.
