If you ignore the ordering, and just consider the raw population counts, then 67 results. If you account for the ordering then a lot more than 67 results.

I only included odd population numbers, as the puzzle says. But the example has even numbers. So I'm not sure what to make of that.

It all seems a bit muddled with the errors and non-conforming examples.
