Small error in this comic. It's not possible to tile a sphere with just hexagons. https://stackoverflow.com/questions/749264/covering-earth-with-hexagonal-map-tiles AlanKilian (talk) 16:03, 8 March 2019 (UTC)

Six triangles form a hexagon - just an explanation for people with less mathematical or geometric knowledge. --Dgbrt (talk) 16:17, 8 March 2019 (UTC)

Yes, but if the triangles are not actually equilateral then they could form a sphere. And if the sphere is big enough (I think solar-system-surrouding or bigger counts) then you probably wouldn't be able to see it with the naked eye. Shamino (talk) 17:08, 8 March 2019 (UTC)
