As it turns out, my simple substitution appears to have been mistaken: it
happened to work for 3 but fails for 4. It looks like the "2&^." argument
to "under" does not vary according to the base. So, the base-n Gray code
generator can be implemented like this:
baseNGray=: 4 : '([:>[:(({. * #@])
One issue is this:
i.@<.&.(3&^.)
Notice that 3%^. is the right verb for the under conjunction. There's
no simple way of passing the 3 in as an argument to that verb.
Does that make sense?
Thanks,

I was recently thinking of a possible use for Gray codes that work in a
base greater than 2. Searching my mail on this, I was led back to a
discussion from 2006 that Dan Bron had kicked off by offering the
generation and conversion of Gray codes as a puzzle.
