Indeed I have been leisurely generating the extremes of the 18C . [ post forthcoming]. Indeed blue has estimated that these box-222222222 puzzles make up ~ 0.75% of all 18C
I think blue and Afmob independantly estimnated with a high degree of certainty
here that there were about
Supersets method - Afmob - 1.9 billion 18C
Grid sampling method - blue - 1.91 billion 18C
Total grids with an 18C : (0.9683 +/- 0.0129) * 10^9 ~ 0.97 billion
60% of grids with an 18C have only one 18C puzzle ,
However it has to be accepted that the the initial generation approach is doomed to only find perhaps 95% of puzzles and never knowingly complete.
The problem lies in that there are many 18C puzzles which are {-2+2} remote of another 18C - so even if we could do a complete {-2+2} we wouldnt find these. Pretty sure thats why
mathimagics has regrouped on the project !
Here is a 2-remote 18C

interesting in that it has empty box 1 and 2, and 4 clues in box 3
and here is ~90% complete list of 154 similar puzzles... which we can probably add most of these to the list
