New lookup screen

[N. J. A. Sloane]

Franklin,   Thanks for those comments.

I agree with the sentiment that the search has been improved
so much that it is not worth tinkering with it any more.

This process has been going on for many weeks now.

Let's declare it a success, and move on.  For my own part, I have
a lot of other urgent projects that I need to work on, 
unrelated to the OEIS.

Of course I will continue to process updates.
