901-beta-n is available.
This fixes a few bugs found in beta-l and beta-m.

Probably worth noting also that I could have instead said:
D=: (+|:)>0;1.5;2 1.5;2.5 2 1.5 0
This is actually one character shorter than my previous expression...

Hi all,
I updated the wiki to include some verbs that will take literal, unicode,
unicode4 or integer types (including 1 and 0 as binary) and return valid
Unicode code point.

I listed all 16 elements of the matrix. It being symmetrical with 0s
on the diagonal, only 6 elements should be needed. Rather than "more
efficient", better word
As Raul says, it’s not clear what you’re after.
An interesting property is shown by:

Yes, we could avoid doubly setting the main diagonal, and could just set the
upper or lower triangle followed by adding the transpose, at the expense of
complicating the code. The
This seems like an underspecified problem.
What do you mean by "more efficient"? (What resource is constrained?)
For example, are you looking for code golf [source code is the
limiting resource] on this specific matrix?
Are you trying to save memory? Are you trying to save time?

Hi Peter,
In my experience, if you do an 'update all' you need to do a restart to get the
base library accepted as updated.

The message is confusing, and I will fix it for 901.
install'all' should get the latest library, but you won't see that until
you restart the session, so it is comparing the latest library with the
current session library.
Enter JVERSION to see your current system. Restart J and enter JVERSION

Hi,
I've installed j807_i386.deb in Debian 10.
https://code.jsoftware.com/wiki/Guides/Getting_Started has advice
"It's a good idea to install all the addons - they provide many useful
functions and don't take much space."
Therefore I did "install 'all' ".
