You mean for a total of 24 right?
so what happens when it gets knocked off the nightstand once or twice and even one (or more) of those "precise angles" get jolted and is off by even a tenth of a millimeter?Reflectius features sixty rotating mirrors that successively reflect a single laser beam at precise angles to draw numbers
comprehension is obviously your problem buddy. first they said 36 in the article not 32, although i'll assume that as a typo. second, from context, you can say that when they put the words 6 "visible" mirrors, obviously there are other mirrors; unless there would be no need for the word visible. and finally from the actual article itself,Where did you read about the 3 non-visible ones? Yes, we can assume that's what the author meant, but that's not explicit. What is is that we have 4 digits with 6 visible mirrors, totalling 32 for some reason, and "even more" invisible ones. The "even more" suggest that there might be more invisible mirrors than the 6 visibles ones per digit. All of that would sum up to more than 48 mirrors.
