Minami-Wakkanai Station
is a railway station located in the city of Wakkanai, Hokkaidō, Japan. It is operated by JR Hokkaido. The station is numbered "W79". Lines Minami-Wakkanai Station is served by the Sōya Main Line from to , and lies 256.7 km from the starting point of the line at Asahikawa. '' Sōya'' and '' Sarobetsu'' limited express trains stop at this station. Layout This is an interchange station with two tracks and one side platform and one island platform (used on one side), connected by a footbridge. Trains generally enter platform 1 on the station building side, and platform 2 on the inside of the island platform is only used when trains, including non-return trains, need to pass each other. Since 2010, the track has been converted to a single track from this station to the end of the track at Wakkanai Station, making this the northernmost station in Japan to have switches, departure signals, and in-station signals.

Cubitruncated Cuboctahedron
In geometry, the cubitruncated cuboctahedron or cuboctatruncated cuboctahedron is a nonconvex uniform polyhedron, indexed as U16. It has 20 faces (8 hexagons, 6 octagons, and 6 octagrams), 72 edges, and 48 vertices, and has a shäfli symbol of tr Convex hull Its convex hull is a nonuniform truncated cuboctahedron. Orthogonal projection Cartesian coordinates Cartesian coordinates for the vertices of a cubitruncated cuboctahedron are all the permutations of : (±(−1), ±1, ±(+1)) Related polyhedra Tetradyakis hexahedron The tetradyakis hexahedron (or great disdyakis dodecahedron) is a nonconvex Isohedral figure, isohedral polyhedron. It has 48 intersecting scalene triangle faces, 72 edges, and 20 vertices.
