Identify the error correcting code. These cards came with my daughter's new toy
I don't see it 😞
I thought ... erm, I'll CW that.
Spoilers, but probably not???
I thought of the holes as binary; there seem to be four locations for them. But Flavours is just one punch away from Counting and Creativity, so it's not just a distance-2 error-detector.
@bmreiniger @christianp Actually, the only way I can think there could be an error here is if the cards were inserted backwards. Of the 16 4 bit sequences, 4 are palindromes (0,6,9,15), of the remainders we see 2,3,5,8,11,14 here and 1,4,7,10,12,13 excluded, so obviously reversed sequences were avoided, but why were those 6 in particular chosen...
