I'm very interested here.
The clue is a recipe. Follow the instructions and you will get an answer.

Can you go into details, Lobster?

I understand the idea that it's a recipe, but I'm interested in how you interpret each step's directions. Do you use digits reading across the sudoku, down the soduku, in each 3 x 3 square?

3. Empty.

Taking this as a stand-alone puzzle (meaning I do not have the book and am only looking at the clue), I can derive two possible answers. (No spoiler font? Oh well.)

My logic says to look at all numbers from 30 and below (if the number is greater than 30 remove it).

Then I removed 5, 10, 15, 20, 25 (if the number is divisible by 5 remove it).

Then I removed 3, 6, 9, 12, 18, 21, 24, 27 (if there is a triplet left over take it out) with 15 and 30 already gone.

Then I removed 1 (since one is the loneliest number).

There are many numbers remaining, but only two of them are perfect squares: 4=2x2 and 16=4x4 (we've elimated 1=1x1, 9=3x3, 25=5x5, and 36=6x6 if it was ever part of the original set).

Now if this whole thing is based on a specific empty sudoko puzzle, that should help you decide which of those is the intended solution. I have no idea why this recipe needs to toss out numbers greater than thirty, unless the sudoko is not the standard 1-9 variety.

The fact that I'm not left with a single answer probably means I've done something wrong, and this cannot spoil the final solve.

(I couldn't edit my own post even within a few seconds of posting, maybe because I used the "quick reply" option? seems unfair)

6. Guys, you're complicating it. (a) you need the book. (b) pay attention to the word EMPTY.

So...do you remove forwards, backwards and/or vertical upside down numbers as well?

For triplets...I took that as three of the same number.

If the rest of the numbers are pairs, then the single number is lonely.

Its possible to get an empty solution depending how you do it?
