@@ -41,8 +49,7 @@ a given block in a way which doesn't change its (unknown) CRC.
 .PP
 The exact behaviour of the CRC is beyond the scope of this manual;
 suffice to say that the result is, in some suitable representation, the
-remainder after division in the finite field GF(2^32) of the block by a
-carefully chosen polynomial of order 32.
+remainder after division by a degree-32 polynomial in GF(2)[x].
 .SH "RETURN VALUE"
 The return value is the 32-bit CRC of the input block.
