I also forgot the 67 rule. Still worked.

Thank you for the nice puzzle. I had forgotten about the 6-7 rule and didn’t need it. If you work with kids, you are no doubt familiar with their preoccupation with these two numbers :-)

Don't really understand worrying that much about memes, but it made for an interesting constraint. Nice puzzle.

Once it got rolling, this was a puzzle where I could solve faster than I could input. I don’t get many of those. Very nice.

Was a bit of a struggle as I had completely forgot about the anti-six-seven rule
