Talk:38 (number)

Comments

According to my calculations based on the definition given by Wolfram [1], the number 38 is neither a factorial prime nor a number that yields a prime when plugged into the function n! +/- 1. Was (38 - 1)! - 1 what was meant? User:PrimeFan

It may well be that this was an error on the original page (Thirty) that I kept when I copied the contents. -- Schnee 22:36, 20 Dec 2003 (UTC)

I think their is a concensus here, so I went ahead and deleted that error. - PubLibGuy

Your all wrong. 38! - 1 is prime. Maybe yall got confused about the signs. Anyhoo, here's what Matematica 4 tells me:

In[2]:=FactorInteger[38! - 1]

Out[2]={{523022617466601111760007224100074291199999999,1}}

In[3]:=FactorInteger[38! + 1]

Out[3]={{14029308060317546154181,1},{37280713718589679646221,1}}

I thinks that settles that. Numerao 22:23, 17 Apr 2004 (UTC)

I ran that through my copy of Mathematica 4 and got the same results, (38! - 1) is indeed a factorial prime. I make mistakes from time to time and my comment above is one example of that. PrimeFan 22:02, 23 Apr 2004 (UTC)

Error in article on number 38.

There is another thing i wanted to point out. It is strange that no one pointed it out earlier. On the article on 38 it says, "38 is the sum of the squares of the first four primes."

So that means, $1^{2}+2^{2}+3^{2}+5^{2}=38$?? But it is not.

According to my calculation, its 39. Can you please check that page and update it.

Sourabh.

1 is not exactly a prime. So you should be looking for $2^{2}+3^{2}+5^{2}+7^{2}$, but that doesn't work either. — The Storm Surfer 19:31, 25 August 2007 (UTC)

William Shakespeare's plays

its says in this article that there are 38 surviving plays by the bard, but the article for 37_(number) states that he only wrote 37, the wiki article for him says 38, but the fact for the 37 plays has a reference, so which one is right? Blah42b10 (talk) 18:13, 8 March 2009 (UTC)
