Therefore Tuza [Tuza 1991] asked for the largest number $s=s(n)$ such that there is a tiling of an equilateral triangle by $n$ equilateral triangles of $s(n)$ different sizes. We solve that problem completely and consider the analogous questions for dissections of convex $k$-gons into equilateral triangles, $k=4,5,6$. Moreover, we discuss all these questions for the subclass of tilings such that no two tiles are translates of each other.", "revisions": [ { "version": "v1", "updated": "2019-03-25T16:13:37.000Z" } ], "analyses": { "subjects": [ "52C20" ], "keywords": [ "convex polygons", "mutually incongruent equilateral triangles", "largest number", "analogous questions", "translates" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
