Diver, the answer to Quiz’s question is that 479 is acceptable for digits in ascending order. I did wonder whether 477 would also be acceptable, but the question didn’t arise in this puzzle.
The answers to B and e differ only in their final digits.
I agree with others that this was in many ways a brilliant construction, but I was surprised to see so many double unches. These used to be forbidden in crosswords, but occur now from time to time. I suppose the editors allow them in cases where it is very hard to find words that fit. But in numericals ??!
