Decades ago, I read an article in Byte magazine discussing various implementations of GoL. The article ended with an implementation in one line of APL. What are the chances you (or anyone) still has that article, and that one line program?
This video constructs a GoL in APL (not one liner). It is quite understandable even if you don’t know APL (I had just started tinkering with APL when I first found it I think): https://m.youtube.com/watch?v=a9xAKttWgP4
In case somebody is curious to see how it might look like.
