how to set mask

[pppp0831]

hi,all
i got a half md5 hash value,and i am sure the password contain some number parts,how to use mask;

hash value E3DC86917650198B
password contain 4 parts: 200002        2018053019184400        100       426
maybe contain the 5th part ,but i dont know what it is 
and the order of that 4 parts is unknow,password length is also unknow.

eg.
halfMd5(200002 + 5th part + 2018053019184400+100+426)  = E3DC86917650198B
halfMd5(200002 + 2018053019184400 + 5th part +100+426)  = E3DC86917650198B


According to this situation,how to set mask ? thank u guys

For each character that you think is a digit, use ?d. If you know parts of it, you can feed that in. Using your example, you can use: 200002?d?d?d?d?d?d?d?d?d2018053019184400100426

But you'll need to guess at how many ?d to use, since you don't know how many characters are missing in there. But the ?d is how you use the digit flag with attack mode 3.

If you don't know the order then yes, you'll need to try all of them, which I think might take a really long time, especially if you don't know how many characters are missing. If you know how many characters are missing, that'd be a huge help for you.
