1 page front and back can be laminated, put into a student's notebook, and used without being lost.

I realized the Reference Card would never be complete, or function as an introduction to J, so I focused on giving examples on the easy-to-forget cases, and mnemonic names for them.

With all due respect, and genuine appreciation for your fine work on the "J
Reference Card"...

IIRC, wasn't the IBM/360 "Green Card" *SIX* pages long?  So, why such an
arbitrary limit for such a rich, and relatively under-documented language
as "J"?

After all, new audiences for J (and uninitiated illiterates like me) need
all the documentary help and more-thoroughly-notated examples we can get --
if J is meant to be more than an esoteric notation!

The multicolor page is the only version that we plan to produce.  Since
the card can't possibly say everything, I am OK with its being incomplete.
  Your point about mentioning all primitives is reasonable. I wouldn't want
to go to more than 2 pages though.

I did the content and layout, and Ric did the formatting.  Since the page
is on the Wiki, anyone with access to the formatting tool Ric used is
welcome to add to it.  If monad /. were to be mentioned, it would be the
last line under Partitions, and would be

                                +--+---+---+--+
    </. i. 2 3   MinorDiagonals |,0|1 3|2 4|,5|
                                +--+---+---+--+

Well, it's impressive what (and how) you got on those two pages.
Perhaps it's worthwhile to extend http://www.jsoftware.com/**
jwiki/Books#J_Reference_Card<http://www.jsoftware.com/jwiki/Books#J_Reference_Card>with
 the J primitives missing.
In the German translation, which covers 3 pages, it is mentioned, under
diagonal.

Is oblique (/.) missing in the J-reference card?
