Several months ago I made a video on a particular terminal access code decrypt problem that I had come across in No Man’s Sky (see above). The given sequence was 1 2 6 24 120. In order to decrypt the terminal and retrieve the valuable information, it was my job in the game to find the unknown 6th term. Can you work it out?

What made this particular sequence interesting, and worth commenting on, is how from a particular vantage point it would appear logically inconsistent. The appearance of a breakdown in logical is such that one might be led to believe that in order to find the unknown 6th term they would have to ignore the 1st term in the sequence. But as I explain, the sequence makes perfect sense in that the deeper realisation here concerns how and why 0!=1.
