Display( C )

Display prints the method of construction of code C. With this history, in most cases an equal or equivalent code can be reconstructed. If C is an unmanipulated code, the result is equal to output of the function Print (see Print).

    gap> Display( RepetitionCode( 6, GF(3) ) );
    a cyclic [6,1,6]4 repetition code over GF(3)
    gap> C1 := ExtendedCode( HammingCode(2) );;
    gap> C2 := PuncturedCode( ReedMullerCode( 2, 3 ) );;
    gap> Display( LengthenedCode( UUVCode( C1, C2 ) ) );

    a linear [11,8,1]1..2 U

U+V construction code of
    U: a linear [4,1,4]2 extended code of
       a cyclic [3,1,3]1 Hamming (2,2) code over GF(2)
    V: a linear [7,7,1]0 punctured code of
