Would appreciate assistance with forming correct command structure

[HelpYourBro]

A quantum computer is not what you want. It would be efficient at breaking the underlying cryptography of litecoin (and bitcoin and most others) but not at calculating hashes.

Cracking a wallet with eight or more unknown characters is unfeasible. The keyspace is too big. I don't quite understand what exactly you know about the password. It may or may not be possible to reduce the keyspace sufficiently.

Thanks. Here is what we think we know:

1) The password is most likely 12 characters, but small chance it is 13
2) it contains numbers, upper case, lower case and special characters
2) The numbers 1,2,3,4,5 and 7 are most likely in the password
3) When 3 occurs it is follow by 2 and then an unknown 
4) When 4 occurs it is followed by 7  and then an unknown
5) When 5 occurs it is followed by 1

for example, it could be 32!*47aA51b9

Do you think that "narrows" it down? Would that suggest a useable set of rules that might make the scope of the effort even remotely reasonable?
