I decided to do this after seeing this tweet thread: https://twitter.com/mperham/status/608750153307017216
and becoming curious if I could come up with a software solution.
It took 1 hour, 25 minutes for me to write code that correctly produces the following solution:
array([[1, 0, 0, 0, 0, 0, 0, 0],
[0, 0, 0, 0, 2, 0, 0, 0],
[0, 0, 0, 0, 0, 0, 0, 3],
[0, 0, 0, 0, 0, 4, 0, 0],
[0, 0, 5, 0, 0, 0, 0, 0],
[0, 0, 0, 0, 0, 0, 6, 0],
[0, 7, 0, 0, 0, 0, 0, 0],
[0, 0, 0, 8, 0, 0, 0, 0]]) 
(it only takes a couple of seconds to run the code itself!)
