Hey! Thanks for You effort. Maybe i didn´t explain myself very correctly. All those irregular hexagons in tile is exactly the same. But they fit if You take same tile and place it on the side or top. I think i have to try this 3 triangle solution mentioned here. I also find some intresting pages from internet. @rich o brien said: I thought the original query was that they have this irregular hexagon shape that fits together in a certain pattern?
