Kaprekar Series

Ha! Finally I published the pages I had created on the Kaprekar routine/series/numbers; also made the code/software for Kaprekar series generation available for public download. Check it out at Kaprekar Series Generator.

Kaprekar Series Site: Site Redesign.

Still working on the Kaprekar Series Generator Site redesign.

The menu on the site still uses a html table. Plan to move that to a pure CSS solution. But currently stumped as to what approach to go for! The current menu which uses table tags is (hopefully!) cross-browser - it will look more-or-less the same across various browsers. Should I move away from that?

Ideally I would like to place the menu in a simple xml structure like -

<div id="Navbar">
<menu>
<menutitle>
<a href="...">Introduction</a>
</menutitle>
<menuitem>
<a href="...">Sample Output</a>
</menuitem>
add other menu titles/items here
</menu>
</div>

And then use CSS to display the above XML (No, I don't want to go the xslt route ... my server side doesn't support it). Something similar to what Project Gutenberg uses for Three Men in a Boat (Excellent book, btw! A must read).

But I wonder if this will be the right approach. What will be the effect of this approach on search engines? Will it effect my (meagre) search rankings? (since the tags menutitle and menuitem will be non-standard).

Another approach will be to use lists (<ul>) tags as detailed in A List Apart. Or the dotted menu demonstrated at Blue Robot.

But I don't see menus as lists and so I'm still confused as to what approach should I go for!

Kaprekar Series Site: Used PHP.

I converted the Kaprekar Series Generator site from a frame based navigation to a php-based site (with the navigation included in the template). Also, I've used CSS ... I'm not sure if it would work on all browsers. I've tested it with Firefox and IE. Lemme know if it doesn't work on your browser.

Playing with Numbers
I finished generating the Kaprekar series for 2-digit to 50-digit numbers. While my pc was still chugging along for larger digits, I looked for "patterns" in the first 50 entries.

I've placed the results in the kaprekar site in a section titled Playing with numbers.
