 #. The fourth line is of the form ``t s r``, where ``t``, ``s``, and ``r`` are, repsectively, the number of generators in bases for :math:`C_2`, :math:`C_1`, and :math:`C_0`.
-#. Each of the next ``t`` lines specifies the bigrade of appearance of a basis element for :math:`C_2`, together with the corresponding column of the matrix representing :math:`f`: the format for such a line is (e.g. if the column has three non-zero entries): ``x y ; b1 b2 b3``, where ``(x,y)`` is the bigrade and the ``bi`` are the row indices of the nonzero column entries.  (Recall that we work with :math:`\mathbb{Z}/2\mathbb{Z}` coefficients.)
