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:

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

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.
1057Please respect copyright.ＰＥＮＡＮＡ45FWFJznWY
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.
