是次創作挑戰有兩個參加方式:

① 翻譯這一道謎題。

② 解答這一道謎題。

兩者可以同時進行,煩請分開為兩個章節。

​標題格式及字數不限。

A particular establishment has a very strict but twisted rule by which people are allowed to enter their premises. The following are allowed to enter:

1. those who are 18 and above and have firearms, wearing sleeveless tops and slippers;

2. those who aren't 18 and above and don't have firearms, wearing neither sleeveless tops nor slippers;

3. those who aren't 18 and above and have firearms, wearing neither sleeveless tops nor slippers;

4. those who aren't 18 and above and have firearms, wearing sleeveless tops and slippers;

5. those who are 18 and above and have firearms, wearing slippers but not sleeveless tops;

6. those who aren't 18 and above and don't have firearms, wearing slippers but not sleeveless tops;

7. those who aren't 18 and above and have firearms, wearing slippers but not sleeveless tops.

If a person satisfies any of these seven rules, they are allowed to enter.

However, people don't even read these rules as they are too much to read for anyone. We can simplify these seven rules further into a fewer number of rules.

What is the least number of rules that these can be rewritten into, such that, again, any person satisfying any of the resulting rules is allowed to enter?

Note:Each rule you write must be a conjunction of two of the four conditions "18 or above," "have firearms," "wearing sleeveless tops," and "wearing slippers," or their respective negations. Thus, for example, a rule like "those who wear slippers or sleeveless tops" is not valid because it's a disjunction.
