### Re: EMDrive and other reactionless propulsion claims

Yeah, you're moving the geometric center of the box but not its center of gravity, so you're not doing any work. Even if you were, the reaction force would push the box back to its initial position, so the total displacement (and thus work) would end up being zero. Aren't there patters of movement ...

### Re: My number is, in fact, bigger!

You aren't making a sequence of strings, just single strings So a is valid, as is ab and abb. The substrings you can't have aren't arbitrary either, but specific ones from n to 2n. So abb is fine because b isn't disallowed, just ab. And later in abbbaa, ab, bbb, and bbaa are the disallowed strings....

A much too large, but still interesting function is where you have a certain number of characters, and you write out strings, each 1 character longer than the last, such that no earlier string is a sub EDIT sequence (my bad) of a later string. It's guaranteed to terminate, and grows stupidly fast. I...

I was going to say that's about A(8,2,1), but it's actually less. It's A(A(8,1,1),1,1) which is between A(2,2,1) and A(3,2,1). Recursion is important, the thing is, you need to use recursion to do more recursion . The effect you're actually seeing here, is where you were using f(n,n,n,n) and f(n,n,n...

### Re: My number is, in fact, bigger!

In the 3 argument Ackermann, A(8) = A(8,0,1) and A(A(A(A(A(A(A(A(8)...))) = A(A(A(A(A(A(A(A(8,0,1),0,1),0,1),0,1),0,1),0,1),0,1),0,1) ≈ A(8,1,1) .

So... yes.

If you would prefer it expressed in the Fast Growing Hierarchy, A(8) = Fω(8), A(A(A(A(A(A(A(A(8)...))) = Fω+1(8)

Well, we're using n+1 as an example, and we reach what we reach. We could use the Ackerman instead of n+1. How much is A(A(A(A(A(A(A(A(8)...))) In the A(n) = A(n,n) version? Because then our function (using the Ackerman) reaches that at: f(8,8) And explodes from there. I.e. it's just a way to recur...
