Indeed, although of course it would be less of a problem for monolith builders as you can't build a monolith that is 0 by 1 by 4. (I was going to put an exclamation mark* at the end of the sentence but realised it could be confused with 4-factorial.)
Incidentally, I recall from the book that the monolith was not merely 3-dimensional, so the sequence continued.
