This pink plastic model has tetrahedral symmetry. There is an indentation with three parallelograms at each corner, Each of these quadrilaterals is coplanar with two others. In addition to having cut away vertices, each side has an equilateral triangle cut out of it at the center. A triangle coplanar with three vertex quadrilaterals closes off the bottom of this hole, with three trapezoids around the sides. A mark on the model reads: 654.
