name: label: maker
content: Wheeler, Albert Harry
notes: label: Description
content: his plastic model has three red faces on the top and another three on the bottom. Each small white triangle in a triangular facet atop the model is coplanar with a large white triangle and two medium-sized white triangles that adjoin it.. This true for a triangular facet on the bottom as well, making for six red faces and six white faces total. The model has nine edges and twenty-one vertices.
label: Description
content: A mark on the side reads: e = 9 (/) k = 21 (/) f = 12 (/) e - k + f = 0. Another mark reads: 709. Wheeler considered this model as composed of two elements of his model 708 (MA.304723.416).
