Alternate-triakis octahedron

The only sites that use the term "Alternate-triakis octahedron" are this page, mirrors of this page, and a page I wrote (and I only used it because this page uses it). Is this name attested in some literature that doesn't show up in a Google search? Are there any other names for the dual of the chamfered tetrahedron? -Apocheir (talk) 21:55, 20 November 2016 (UTC)[reply]

Sorry, it was a best effort at a descriptive name. Conway polyhedron notation has a semi-kis operator on even-valence polyhedra, related to semi-truncate. So it could be a semi-kis octahedron. Tom Ruen (talk) 19:09, 19 September 2017 (UTC)[reply]

For polygons, it triples the number of vertices...

How I can construct chamfered polygon? What will be chamfered square? Jumpow (talk) 13:02, 4 March 2018 (UTC)[reply]

Think of it as a double-sided truncation where original edges get shorter and 2 new edges appear around the original vertex. So a chamfered square is a dodecagon. Tom Ruen (talk) 16:39, 4 March 2018 (UTC)[reply]
