Find the code table for $(7,4)$ division cyclic code generated by

$g(p)=p^2+p+1$Example: Write down the code table for the $(7,4)$ nonsystematic cyclic code with generator polynomial g$($x$)=$x$^3+$x$+1.$ Example: Write down the code table for the $(7,4)$ systematic cyclic code generated by the generator polynomial g$($x$)=$x$^3+$x$^2+1.$ Here n$=7,$ k$=4,$ r$=3$ : $1$
