This file specifies the sparse 83x174 parity-check matrix for the
FT8/FT4 (174,91) LDPC code. Each of the 174 columns contains
exactly 3 ones. The rows contain either 6 or 7 ones.
The matrix is specified by the following list consisting of
174 lines, each of which includes 3 numbers.
Each line corresponds to a column of the parity check matrix.
The three numbers are indices of the rows that contain a one in
the corresponding column. The indices range from 1 through 83.
