@bof Yes, that's correct.

$6×19$ doesn't work, but $6×27$ does.

Other than $2×n$, $6×11$ is the smallest example, and $6×15$ the next smallest. I'll let you know when my computer reaches $6×19$...

That's pretty much exactly what I was looking for - a place to start. :) Thanks!

I believe that the current "consensus" (if such exists - it's at least a trend) on periods at the end of quotations is predicated on whether or not the period belongs with the quoted sentence - (He said, "No, thank you.") vs (He spoke about "stuff".)
