You must provide more context.
How can a sequence be shifted?
When we consider two different

how can we tell that one is a shifted

For example, a Doppler shift preserves the relative sequence of the

Frauenhofer lines, but shifts their absolute position.

Let be S = {s1, s2, ..., sn} be some sequences.

Here is a new sequence Q = {a, b, s1, s2, ..., sn},
i.e. Q is twice/double/doubly(?) shifted sequence S with two added elements ('a' and 'b').

How can we tell Q is S altered twice?
What would inform us if Q were S altered once or three times?

Here are a few ways to express the definition of sequence Q:

Sequence Q is the same as sequence S, with the elements 'a' and 'b' inserted
at the beginning.
Let Q be a sequence identical to S with its elements shifted two places to
the right, and with 'a' and 'b' as its first two values.
Element N of sequence Q is equal to element N-2 of sequence S, where N > 2.
The first and second elements of Q are 'a' and 'b' respectively.

Or you could just define the mathematical relationship between them:

Q[x] = S[x-2] (x > 2)
Q[1] = 'a'
Q[2] = 'b'

I would write "a/the doubly shifted sequence", or "a/the sequence
shifted by two (steps or places)". I think "twice shifted" would be
passable, but I don't much like "double-shifted", even with the hyphen.

I have been uneasy about your question. It has now become clear why.


Consider the following:

take the sequence of letters

ABCDEFGHIJKLMN

shift(n) is an operation that shifts each letter
n positions.

(For convenience the shift will be circular - letters that
fall off one end will reappear at the other.)

shift(1) applied to ABCDEFGHIJKLMN results in
NABCDEFGHIJKLM

shift(3) applied to ABCDEFGHIJKLMN results in
LMNABCDEFGHIJK

shift(-1) applied to the above sequence,
LMNABCDEFGHIJK, results in
MNABCDEFGHIJKL

As you will see, to me, "shift" is a general function that can in, a single
operation, move the sequence any number of places in a left or right
direction.

In that context "twice" or "doubly" shifted would mean two successive
applications of the shift function - shift(n) followed by shift(m).

However, in your question you use, without definition, "shift" to mean only
a one place movement to the right - in my mind: shift(1).

If in the context of your question the shifts are only ever in one
direction, instead of:

Quote:
twice shifted sequence
double shifted sequence
doubly shifted sequence

I would suggest something like:

"sequence shifted two places"

This is "futureproof" in that if you ever need to refer to a larger shift
you will not be left pondering: "once, twice, thrice, err, umm, what's
next?", or the equivalent with double or doubly.

Q.

I would think you should ask people in the Sequence Community, not an
English language newsgroup. Unless this involves a new idea, people
in that field who speak English should already have a term for what
you want.

To a programmer, `doubly shifted sequence' conjures a sequence than can
be shifted in either direction, such as a `doubly linked-list', whose
every element points not only to the next element but also the one before
it.
