`ainf` |
A vector of informational integers for the factored "a" matrix.

`linf` |
A vector of informational integers corresponding to the least

i-th entry is |

`f` |
A copy of the factorial values calculated for various internal length determinations. |

`a` |
A copy of the internally generated factored "a" matrix. |
