Would anyone happen to have at least some rough idea of when Odlyzko was born? The brief bio on his website would indicate he's at least 26 years old. Very tight-lipped about this for some reason.

At the First Monday conference a few months ago, I met Odlyzko in
person. While I don't know his age, I can tell you he's a lot
older than 26! He looked more like twice that age to me. Joe and
Aaron were there with me; maybe they are better at guessing ages
then me and can come up with a good guess.

The first publication he lists on his site is from 1970, so he must be at least 36 years old. :P

To know more about these Google OEIS and see
Seq A123239.

Several questions:

1) Why are they called "mangammal"?

2) Do you mean 3^(n - 2) or (3^n) - 2?

3) Who is the author of ISBN 1550-3747? Is that ISBN number complete?

4) What's one interesting thing about these primes?

1) "Mangammal" is the name of my late mother

2) Your second option is right

3) This is the reference No of Hawaii Intl Conference on
Statistics,Mathematics & related fields

4) Excepting 2^n-1 all exponential functions with the shape

a^n + c (a & c belong to N and are fixed; n is a variable belonging

to N) have a set of "impossible factors"; Mangammal primes is

only a demo of this.

A MINOR CORRECTION

c belongs to Z and not N.

How do I add "Mangammal Primes" to Maths Encyclopedia pl?
A.K.Devaraj

Go at
http://planetmath.org/browse/objects/11A41/
Choose: 44. prime
Roll down to the bottom at the Interact bar and choose: add(any).
Once you're there do the following.
Type: choose: Topic
Title: Mangammal primes (if Mamgamal is not a proper name, then write mamgammal)
Attached to (if applicable): Leave it in blank (remove Prime)
Classification (See MSC): msc:11A41 (it is ready, leave it so)
Roll down to:
Content (edit your LaTeX here. See PlanetMath Content and Style Guide , or Syntax Help ): (this is the blank LaTex page where you will write)
Begin to write your entry.

Thank you very much.I will try to follow your instructions; hope
I succeed.

A. K. Devaraj,
you entry does not render for page images and HTML with images mode, but I see its source text. Seems interesting!
Please put the dollar signs only in math expressions, i.e. now edit your entry to the form

Mangammal primes (named after my late mother) are the impossible prime factors of $3^n-2$. See the sequence A123239 of OEIS.

Please, add some exemples, too.

Regards,
Jussi

If you don't know TeX, PM has a pretty good guide: http://planetmath.org/?op=getobj&from=collab&id=120 Though it's still incomplete in regards to calculus, it should have everything you need as far as topics in elementary number theory are concerned.

Thank you very much.I have successfully entered "Mangammal primes" in the Encyclopedia.I forgot to add that they are named after my late mother,Mangammal.

A.K.Devaraj

You are welcome! But born twins.

I think I have finally edited successfully both "Mangammal primes" and "Shantha primes".I have also deleted the superfluous entries.
I would like to thank all those who helped me to do so.
