Mafia 84. Memorized it, turned it in, forgot it!

Perhaps there's a way to match these letter combinations with numbers, to find some kind of pattern.

I'm more than sure that's the case. Perhaps, "cl-", which resulted from "sd-", is just a coincidence, because the other elements don't become clearer this way.

And by the way, since I'm the one who has to speak for Gekasan, I'd like to ask him a question: "Why isn't he solving the clue?" and "Why is he happy that psychology pointed him to me?" Ah, Gekasan? I, at least, am trying to do something, but you just cast your vote and left, complaining about the "difficult clue." That's not how things are done.
