O'Brian code

Redirect to:

• Gray code#O'Brien

• To a related topic: This is a redirect to an article about a similar topic.
  • Redirects from related topics are different than redirects from related words, because a related topic is more likely to warrant a full and detailed description in the target article. If this redirect's subject is notable, then also tag it with {{R with possibilities}} and {{R printworthy}}.

• From a misspelling: This is a redirect from a misspelling or typographical error. The correct form is given by the target of the redirect.
  • This redirect is made available to aid searches. Pages that use this link should be updated to link directly to the target without the use of a piped link that hides the correct details.
  • This template tags redirects with a subcategory of the Redirects from incorrect names category, so template {{R from incorrect name}} should not be used with this template.
