A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi
Time to bring out the envelope again so we can do some calculations on the back of it. So 2.4 trillion permutations is 2.4 million times that, or 12 million seconds. That's somewhere over 3,000 hours  close to 20 weeks in fact.Currently I can generate around 1 million permutations in 5 seconds.

Well, do have fun. But keep the back of that envelope handy. From what I've seen, there does seem to be a small number of patterns in published Sudoku puzzles, but maybe that's more because it's easy to generate them that way. But to get there, you're going to have to go past enumerating all possible solutions and start enumerating all solvable problems.And I'm not overly concerned with the time issue here. This is just a fun project for me.
Don't get me started about those stupid light bulbs.
