"possible number combinations" of different numbers of integers -.

Depends what you define as "combination" but anyway - your
solution should be found here:

Hi, sulprobil:

I wonder if most folks have the right tools to work with Knuth's files.

I followed your link to his site. The links on the page are to GZ files (some
kind of archive/zip file that I don't recognize), but luckily I have a program
that can open GZ files. Once I got that far, I found the archive content to be
a Post Script file. Since I have Adobe Acrobat, full version, I was able to
convert that to a PDF file.

On further exploration, I found Knuth's page has a link to an unzipper,
GZIP.EXE, and another to GhostScript, which can be used to view the PS file.

gzipped - standard archive format on all Unix/Linux/BSD systems, an
incorporated into nearly all Windows archiving programs written fro
2000 on.

You've already mentioned GhostScript as an alternative way to view P
files (or convert them to PDF, HTML or plain text). There's also
shareware PS viewer named RoPS and an open source viewer/converte
named MakePDF (still in beta)

Hi, Harlan:

Since I've never used a Unix/Linus/BSD system (or a Mac), their file formats
are all Greek to me.

FWIW, WinZip v8 *can* handle the GZ format (as well as PowerDesk, the program
I normally use).

Thanks for the additional info on viewing PS files. I checked out RoPS. It
works OK, but the down side (for me, considering the use I would get from it)
is the cost: $45. I guess I'll stick to converting to PDF, since I have the
full version of Acrobat 6.

But you have a thorough understanding of .zip file layout?

File formats are common across OS's using the same character set (i.e.,
files do differ EBCDIC vs ASCII, but don't differ much among ASCII-based
OS's).

FWIW, WinZip v8 *can* handle the GZ format (as well as PowerDesk, the
program I normally use).

As can PowerArchiver, which I normally use. These days I'd guess everything
other than perhaps PkZip can support all compressed archive formats that
have ever been. FWLIW, there's also bzip (.bz) format, which can usually
attain greater compression that .zip or .gz. PowerArchiver supports it.
