And what would you use if you need a noun? Normal form? Again, more of a
mouthful.
Other terms I would use for identity problems, when explaining to laymen,
is "ID number". They usually get it immediately.

I like “normalize” personally.
The ideas I associate with “signature” are not robust enough for a reliable
nub (and so would require additional care elsewhere).
If that matters...

In this context, I prefer words like signature or representative rather
than canonical form. Shorter and less scary and puts one's mind on the
right track in multiple problems.
e.g. What's a good representative for identity problems? ~. i. ] (index
in nub). What's a good representative for ord
This is what I was looking for. It works on REB's testcase but has less

NB. Get # left-shifts to canonicalize y
canonshift =: 3 : 0
NB. Try each atom of y until we find one that works

A possible version of the signature verb:
sig=: |.~ >:@(# -~ {: i. 1:)@min
min=: (_1 |. ] #^:_1 (= <./)@#~)^:(1 < +/@])^:a: 1"0
Perhaps not the fastest version, but it’s light on memory.

The first cuts down on the number of rotations...
sig =: 3 : 0
min =. {. @: (/:~) y
imin =. I. y = min
{./:~ imin |."0 1 y
)
This second looks at pairs. Unchecked as rushing off...
sig2 =: 3 : 0
min =. {./:~ ~.2 ,/\r =. (,{.) y
imin =. I. r =
Yes, well, left as an exercise for the reader. :-)
Idea: the minimum rotation of a vector necessarily begins with its minimal
item.

Yes; but now suppose the lines are very long. Is there a way to find
the signature (I would call it a canonical form) that doesn't require
enumerating rotations? (I haven't found a good way yet).

For each row, find a "signature", then find the nub sieve of the
signatures. The signature I use here is the minimum of all possible
