Thanks, Louis.
I've just taken ownership of Ch 26 (the essay in question) and I've noted
your comment.
In the course of revision I will reconcile the FSOJ definition of a group
with the conventional one used by abstract group theorists.

I don’t know if this is the right place for this, but I just read through the
beginning of a few sections, and looking at the one on groups I found the
mathematical definition of a group kind of peculiar, in particular point (c):
« every element e has a left and right inverse, that is there are
Thoroughly agree, Chris.

These suggestions on spacing are interesting, but I am concerned that they
divert attention away from the main focus, which is to recruit volunteers
to make sure the code and text in each essay is technically correct.
There is no generally agreed spacing convention for J code, so it is really

@Henry – in my heart-of-hearts I know you're right. But it's lifted off the
launchpad now.
I've scratched my chin about a final application of some agreed spacing
convention – a J app to do that is badly needed. But how to do it without
invalidating the testing? It could call for a really smart bo

I think it's a mistake to leave it to individuals. Spacing really makes
a difference to readability.
Using a special font and something to set off the J code would help.
Maybe have a gray background box around code.

Can I recommend these prettyprinting conventions apply only to J code

Inline J within narrative text (…) is something else altogether.
It is fraught with readability issues and often demands creative solutions.
If there's one general rule, it is: have as few spaces as
Yes, what we did for the second edition of At Play with J was to get the
wiki version correct, and then get it published as a book. Putting it on
the wiki allowed many people to check and update the work first.
We are interested doing the same with FSOJ.

why not use PDF format and create a downloadable book. id pay for it!

Allright, I came back to this today, and the macro theory doesn't hold for
wmove, which is definitely not a macro, but fails with the same symptoms:
stdscr_ncurses_ =: initscr''
w =. newwin 20;60;0;0
wmove w ; 10 ; 10
wgetch < w

I agree with all those suggestions. I would add a space before the LHS
of assignment, and I would allow extra spaces around parentheses to make
it easier to match parentheses by eye.

No space if possible between modifiers and verbs.
The convention used throughout topics appear to be no spaces ever.
