Solution to SrImati rAjammA's problem

jkmrao's picture

As I mentioned in my hint, the original motif redrawn on a hexagonal grid, was placed at the centre (in red) and around it six (in dark blue and light blue) more were arranged so that they are all in close contact. Around this second layer, 12 more (in purple and pink) were fit. Six more (in orange) were placed in the fourth layer. We have thus 1+6+12+6 = 25 basic motifs. Actually the fourth layer is not full. There must be 18 in the fourth layer. In the figure on the right side, I filled all the 18 (in orange, red and rose). This is more full without leaving any vacancy. In this there are 1+6+12+18 = 37 basic motifs. If the next layer is similarly filled, there will be 24 in that. The over all basic symmetry is only three-fold. This type of exercise educates one as how to fill motifs and create a lattice with translational symmetry. Crystals are filled with such molecules infinitely along the three directions in three dimensional space. Enjoy!

Superb. Both the outcome are the real perfect solutions. And your explanation will give the members to invent and also solve such puzzles.Thank you Sir for taking such interest and encouraging and educating us. In the first two puzzles I wanted to mention that members should go thru your gallery to get some idea or guidance to connect similar patterns, thereby craeting different design in the gap!
But the response was poor. So I left it. But I wrote that for mOhanaji these type of puzzles will be "Jujoobee".
Sir, Smile Can I request you to give some work like this to freshen up our brains?
