Starting in 24 hours, unless somebody objects, if somebody guesses a rule and there is a yes counterexample, I’ll give that in preference to no counterexamples; that is, I will confirm superset rules as such. Alternately, I can give another free yes which I expect will help.

Nobody has responded to either proposal, so I’ll give the other string and do the superset confirmation if somebody asks me to.

Yes: 8521

Guess: Substrings of ab6221020798521f1f5f8fce4

That is incorrect. Did you want me to give a superset confirmation or rebuttal if applicable?

Since you did not ask for that I will not give it. Instead I will point out that 20 is a substring of ab6221020798521f1f5f8fce4 but is on the no list.

How did you come up with this guess, out of curiosity?

Yes.

I smashed together everything on the yes list.

102
198521
298521
398521
498521
598521
698521
798521
898521
998521

In that case I will add a yes counterexample to it, generated randomly:

Yes: 5ef8

I am not basing this off a random secret hexadecimal string.


And for your guesses:

Yes: 102, 498521
No: 198521, 298521, 398521, 598521, 698521, 798521, 898521, 998521
