I would suggest that all ambiguities are resolved by example. In this case, the following would seem to apply:

4824: 4 Ort, because in place of the first digit the words Torf, fort, Tor could be used

I read that to say, that as 'aaa' can be applied at the first step, inserting a digit at that point is illegal. Therefore your example has no solutions.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice.
