+M4RI is a library for fast arithmetic with dense matrices over F2. The name M4RI
+comes from the first implemented algorithm: The "Method of the Four Russians"
+inversion algorithm published by Gregory Bard. This algorithm in turn is named
+after the "Method of the Four Russians" multiplication algorithm which is
+probably better referred to as Kronrod's method.
