This cut and taped paper model has three triangular sides going inward on the bottom to meet at a point. Around the outside are three triangles that adjoin these sides as well as six additional triangles that meet in pairs at vertices of the base. One side is disconnected. A mark on it reads: e - k + f (/) 9 - 21 +12 = 0 (/) July 31, 1931 (/) OK. A paper tag reads: 721.
Wheeler described the model in his manuscript catalog as "not finished." He gave it the additional number M80.
