My row vector runs off the page in an `align*` environment

Question

I am trying to format a row vector with fifty columns such that it remains on a single page (perhaps over multiples lines). The vector is in an align* environment. My code is shown below

\begin{align*}
 \mathbf{y^*}&=\left(x_1,\dots,x_{50}\right) \\
 &=\left(7, 1, 1, 1, 0, 1, 7, 8, 40, 1, 0, 0, 1, 0, 1, 0, 0, 1, 0, 1, 1, 0, 1, 0, 1, 1, 11, 0, 1, 0, 1, 1, 0, 1, 0, 1, 1, 0, 9, 1, 0, 1, 0, 1, 0, 1, 1, 2, 0, 1 \right)
\end{align*}

How can this be formatted such that the vector does not run off the page.

Edit

\usepackage{amsmath}
\usepackage{setspace} % for "\setstretch" macro
\newcommand\mybox[1]{\parbox[t]{0.75\textwidth}{
\setstretch{1.33}\raggedright$\displaystyle #1$}}
\begin{align}
\mathbf{y^}&=(x_1,\dots,x_{50}) \
&=\mybox{(7, 1, 1, 1, 0, 1, 7, 8, 40, 1, 0, 0, 1, 0, 1, 0, 0, 1, 0, 1, 1, 0, 
1, 0, 1, 1, 11, 0, 1, 0, 1, 1, 0, 1, 0, 1, 1, 0, 9, 1, 0, 1, 0, 1, 0, 1, 1, 
2, 0, 1)}
\end{align*}

Another idea

\begin{equation*}
\begin{split}
\mathbf{x^*}=&\left(x_1,\dots,x_{50}\right) \\
=&(7, 1, 1, 1, 0, 1, 7, 8, 40, 1, \\ & 0, 0, 1, 0, 1, 0, 0, 1, 0, 1, \\ 
 & 1, 0, 1, 0, 1, 1, 11, 0, 1, 0, \\ & 1, 1, 0, 1, 0, 1, 1, 0, 9, 1, \\ & 0, 
 1, 0, 1, 0, 1, 1, 2, 0, 1)
 \end{split}
 \end{equation*}

@azetina I tried to follow their method. I used the packages in the example and altered my column vector to \mybox{(7, 1, 1, 1, 0, 1, 7, 8, 40, 1, 0, 0, 1, 0, 1, 0, 0, 1, 0, 1, 1, 0, 1, 0, 1, 1, 11, 0, 1, 0, 1, 1, 0, 1, 0, 1, 1, 0, 9, 1, 0, 1, 0, 1, 0, 1, 1, 2, 0, 1)}. However, the vector still runs off the page. — M B, Nov 18 '20 at 07:22
Can you update your question so that we can see how you implemented the technique? — azetina, Nov 18 '20 at 07:25
Maybe tedious, but putting the data in a sub array would be easier in this case. — azetina, Nov 18 '20 at 07:34
Try this: \documentclass[letterpaper]{article} \usepackage{amsmath,array} \begin{document} \begin{align} \mathbf{y^} &=\left(x_1,\dots,x_{50}\right) \ &= \begin{array}[t]{@{}r@{}{9}{@{\ }c<{,}}@{\ }c@{}l} (& 1 & 1& 1& 1& 1& 1& 1& 1& 1& 1,& \ & 1 & 1& 1& 1& 1& 1& 1& 1& 1& 1\phantom{,}&) \ \end{array} \end{align} \end{document} — azetina, Nov 18 '20 at 07:56

With use of the package \linegoal:

\documentclass{article}
%---------------- show page layout. don't use in a real document!
\usepackage{showframe}
\renewcommand\ShowFrameLinethickness{0.15pt}
\renewcommand*\ShowFrameColor{\color{red}}
%---------------------------------------------------------------%
\usepackage{amsmath}
\usepackage{linegoal}
\begin{document}
    [
\begin{aligned}
\mathbf{y^*}
    & = (x_1,\dots,x_{50}) \
    & = \parbox[t]{0.8\linegoal}{
        (7, 1, 1, 1, 0, 1, 7, 8, 40, 1, 0, 0, 1, 0, 1, 0, 0, 1, 0, 1, 1, 0, 1, 0,
         1, 1, 11, 0, 1, 0, 1, 1, 0, 1, 0, 1, 1, 0, 9, 1, 0, 1, 0, 1, 0, 1, 1, 2, 
         0, 1)
         }
\end{aligned}
    ]
\end{document}

For final result need to be compiled twice:

(red lines indicate page layout)

A couple of ideas

\documentclass{article}
\usepackage{lipsum,amsmath}
\begin{document}
\lipsum[75]
\begin{multline}
\begin{aligned}
\mathbf{y^}
 &= (x_1,\dots,x_{50}) \
 &= (7, 1, 1, 1, 0, 1, 7, 8, 40, 1,
\end{aligned}
\
0, 0, 1, 0, 1, 0, 0, 1, 0, 1, 1, 0, 1, 0, 1, 1, 11, 0, 1, 0,
\
1, 1, 0, 1, 0, 1, 1, 0, 9, 1, 0, 1, 0, 1, 0, 1, 1, 2, 0, 1)
\end{multline}
\lipsum[75]
\begin{align}
\mathbf{y^}
& = (x_1,\dots,x_{50}) \
&= \begin{aligned}[t]
   (& 7, 1, 1, 1, 0, 1, 7, 8, 40, 1, \
    & 0, 0, 1, 0, 1, 0, 0, 1, 0, 1, \
    & 1, 0, 1, 0, 1, 1, 11, 0, 1, 0, \
    & 1, 1, 0, 1, 0, 1, 1, 0, 9, 1,\
    & 0, 1, 0, 1, 0, 1, 1, 2, 0, 1)
   \end{aligned}
\end{align}
\lipsum[75]
\begin{align}
\mathbf{y^}
&= (x_1,\dots,x_{50}) \
&= (
\begin{array}[t]{@{:}c{9}{@{;,;}c}}
7 & 1 & 1 & 1 & 0 & 1 & 7 & 8 & 40 & 1 \
0 & 0 & 1 & 0 & 1 & 0 & 0 & 1 & 0 & 1 \
1 & 0 & 1 & 0 & 1 & 1 & 11 & 0 & 1 & 0 \
1 & 1 & 0 & 1 & 0 & 1 & 1 & 0 & 9 & 1 \
0 & 1 & 0 & 1 & 0 & 1 & 1 & 2 & 0 & 1 \rlap{$:)$}
\end{array}
\end{align*}
\end{document}

I tried using the \equation* environment (I have placed the code in my post). Though, I don't like the look of it. It would look better if the first entries in subsequent rows vertically aligned with the first entry of the first row. – M B Nov 18 '20 at 07:56
@MB I've added an alternative. – campa Nov 18 '20 at 08:06
This is perfect. Obviously I can ignore the lipsum*[4] and only take that within the align* environment, right? – M B Nov 18 '20 at 08:15
@MB Of course, the \lipsum is just for the dummy text. I have added yet another version. – campa Nov 18 '20 at 08:17
