The program constructs girth-twelve column-weight QC-LPDC codes. The rate can be changed by changing k(row-weight), size is changed by varying m(sub-matrix size). The program/algorithm does not guarantee to get girth twelve code. It guarantees girth of eight. One may need to run the programs many times to get girth of twelve.

The previous version construct a code even when it failed to find a row satifying the desired distance. In the new version the algoirthm quits when it fails. Extra conditions are added to avoid eight-cycles.
