 .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\*(ss32\*(se) of the
-block by a carefully chosen polynomial of order 32.

 .SH "RETURN VALUE"
 The return value is the 32-bit CRC of the input block.
