Hi J, Your blog is just Wonderful. Small question: In the first case, why aren’t we considering bead and necklace logic that flag can be turned upside down! Then it should be divided by 2!. Thanks Reply
Because a flag has a specific end which is attached to the pole, so changing the orientation gives us a totally different flag! See this link for some examples 🙂 http://www.newsonaut.com/countries-with-almost-nothing-in-common-but-their-flags regards J Reply
