Nice work, thank you Karvina team. It's interesting that you were looking for numbers, while we were mostly chasing Geometry. You have added the missing piece of the puzzle! :)
that's right! We are surrounded by numbers from the very beginning of our life! In fact, Spanish citizens as many others in the EU have a National Identity Card with a number. which we are, more or less, obliged to know by heart. congratulations for this work.
