86 is the middle number in the second cluster of three discrete biprimes between 85 and 87 being themselves discrete biprimes.

86 is a semiprime, nontotient, a noncototient, a happy number, and a self number. It appears in the Padovan sequence, preceded by the terms 37, 49, 65 (it is the sum of the first two of these).

Since it is possible to find sequences of 86 consecutive integers such that each inner member member shares a factor with either the first or the last member, 86 is an Erdős–Woods number.

In American English, the number 86 used as a verb, to "eighty-six," means to "ignore" or "get rid of". The first recorded usage of this term occurs in the mid-1930s. There are many theories of the origin of this usage, most pertain either to death or to prohibition.

Origin

Of the explanations pertaining to prohibition, one is a reference to Article 86 of the New York state liquor code which defines the circumstances in which a bar patron should be refused service or "86ed".^{[citation needed]} Others have suggested that this usage originated from the famous Delmonico's Restaurant in New York City, as item number 86 on their menu, their house steak, often ran out during the 19th century.^{[citation needed]} However, there is no recorded usage of this term in the nineteenth century. Yet another explanation is that Chumley's, which was a famous 1900s New York speakeasy, is located at 86 Bedford Street.^{[citation needed]} During Prohibition, an entrance through an interior adjoining courtyard was used, as it provided privacy and discretion for customers. As was a New York tradition, the cops were on the payroll of the bar and would give a ring to the bar that they were coming for a raid. The bartender would then give the command "86 everybody!", which meant that everyone should hightail it out the 86 Bedford entrance because the cops were coming in through the courtyard door.

The term "86" in a bar, nightclub, gentleman's club etc. refers to the status of a person who is no longer welcome at or legally able to enter the establishment.^{[citation needed]} A person who has been "eighty-six'd" has been kicked out of the establishment, usually permanently. The most common reasons for a customer to be permanently removed from an establishment like a bar or club is inappropriate behavior inside the establishment.

Also in restaurant/bar terminology "86" is a phrase that is used internally between employees to communicate to each other that a specific food or beverage item is sold out or out of stock.^{[citation needed]} e.g. "'eighty-six' the crab cakes" means that the establishment is sold out of crab cakes. Another variation of the term 86 can be to illustrate the removal of a specific item from a food order, for example, if a patron wishes to purchase a cheeseburger without lettuce or tomatoes a server can place the order as cheeseburger, 86 lettuce & tomatoes.

All these explanations are associated with a specific origin, but there is another which would seem to have a universality which on one hand makes it a plausible origin, but on the other hand may be too simple to be true; the dimensions of a grave hole being dug to 8' by 6'. This has a problem though in the standard dimensions being a lot closer to 7' by 6'.^{[citation needed]}

Restaurant code and all other theories so far mentioned aside, one hypothesis as to the term's origin appears to hold water, at least in so far as no part of it seems to run counter to any other part. 86 is rhyming slang for nix, a word meaning 'to forbid, refuse, veto' (as in "The boss nixed my great plan for reorganizing the company"). Nix carries a clear meaning of 'say no to, turn down, forbid,' which is the primary meaning ascribed to 86. Yet unlike other theories about how 86 entered the language, neither are there supposed earlier forms conveying a different meaning (e.g., the restaurant code), alternative forms the terms could more reasonably have taken (Chumley'd), nor documentary evidence supporting the posit's claim (liquor codes that included an Article 86 having something to do with barring service to a potential customer). Nix therefore appears the more likely of all the conjectures.

Whether it was the catalyst that propelled 86 into American culture, or just helped reinforce it, in the late Winter of 1960, the movie: Visit to a Small Planet, starring Jerry Lewis was released. Jerry Lewis plays the part of Kreton, an alien with special powers. To activate his powers he used number commands, one of which was 86, and that destroyed things. He kills a plant by saying 86 and later threatens to kill a guy with the same command number. Just as every kid came out of the Rocky film saying "yo, Adrian" all the kids came out of this movie pointing their fingers at each other and saying "86".

In sports

For many baseball fans, the most popular if misplaced reference was born of the 1986 playoff debacle for the Boston Red Sox.^{[citation needed]} Game 6 and (eventually) the World Series slipped through the glove of first baseman Bill Buckner in the bottom of the 10th inning. The Sox didn't recover from the letdown in time for Game 7 and the New York Mets took the '86 crown. With Red Sox fans long considering the team to be cursed from trading Babe Ruth for cash and the 1986 World Series representing the closest shot the team had at winning the World Series in decades, the term '86 took on the meaning of "not happening." For football fans, "to 86" still means "to get rid of," for example, in the Cincinnati Bengals, Chad Ocho Cinco fittingly wears jersey #85, which, coupled with his desire to leave the team, has led to fans urging the Bengals to '86 85'.
