Ha! We decided to make a version of these for kids at our microschool (with their faces on the cards) for an end of year gift. Didn't realise the math was going to tricky. Found a page with code to generate combinations. Luckily, being a microschool meant we had the right number of kids plus educators for a small pack that covered all of them equally. Was fun diving into it and the kids loved the cards.

There is Møbee, a new, similar game, that has a common symbol between any three cards. The mathematics of that deck is based on finite Möbius planes.<p>[0] <a href="https://mobeecards.store/homepage/" rel="nofollow">https://mobeecards.store/homepage/</a>
