Code -- a code as image

Description

Given a linear code C, this symbol is used as a key for storing C as the image of some mapping between finitely generated modules, where each module is over the same Galois field.

This symbol is provided by the package CodingTheory.

i1 : C = linearCode(GF(8,Variable => b), {{1,1,b,0,0},{0,b,b,1,0},{1,1,1,b,0}});
i2 : C.Code

o2 = image | 1 0 1 |
           | 1 b 1 |
           | b b 1 |
           | 0 1 b |
           | 0 0 0 |

                                     5
o2 : GF 8-module, submodule of (GF 8)

For the programmer

The object Code is a symbol.
