I was unsure how to categorise this page on Bohm's language P", and hope someone will remedy that. --(this comment by R.e.s. at 23:02, 15 July 2005‎ UTC; please sign your comments with ~~~~)

Given that it's described as "describing a proper subfamily of Turing machines" - and that there's no indication that it was ever intended to be implemented or otherwise used as anything except a formalism - I would guess that Category: Computational models is probably the place for it. --Chris Pressey 18:29, 16 Jul 2005 (GMT)
I disagree, since it looks like a language in basically every other respect, and besides, the year categories are only meant to be applied to languages in Category:Languages. I've filled out more categories (seven years later). —ehird 18:51, 16 April 2012 (UTC)
But now I'm having second thoughts, and wondering whether that criterion for the year categories is a good idea after all. Bah. —ehird 18:55, 16 April 2012 (UTC)


Is everyone else seeing the name of this language as horrendously formatted as I do? (I.e. P′′ with the prime marks far apart.) Perhaps we should change back to apostrophes, even if it isn't technically correct? --Ørjan 22:58, 21 March 2007 (UTC)

Not sure what you're seeing -- it looks fine to me. --r.e.s. (Talk) 06:21, 22 March 2007 (UTC)

I tried to make a redirect that would send P-prime-prime to this page, but it doesn't seem to work. (I think spelling it out as P-prime-prime is the best, because it's both easy to remember and avoids special characters or any characters that confuse the Wiki.) Anyone able to make the redirect work? --r.e.s. (Talk) 13:03, 15 November 2007 (UTC)

Me neither. Maybe moving P'' to P-prime-prime is better? Except I think underscores are more common than hyphens. --Ørjan 19:17, 15 November 2007 (UTC)

I finally got it to work. The title of the present article is actually P followed by two single quotes (which is natural enough on the keyboard, but unfortunately confuses the Wiki.) --r.e.s. (Talk) 20:30, 15 November 2007 (UTC)

Proper name

As "the guy" is a mathematician are we sure that the name is a P′′ not Ρʺ ?

In case you're still having trouble with your fonts, that is: "U+03A1, GREEK CAPITAL LETTER RHO" followed by "U+02BA MODIFIER LETTER DOUBLE PRIME" 2001:470:1F09:10D6:3493:51E6:3757:8DCC 09:07, 5 August 2013 (BST)
