4.2. Corollary 2

   If s' is the result of adding the non-zero integer n to the sequence
   number s, and m is another integer from the range defined as able to
   be added to a sequence number, and s" is the result of adding m to
   s', then it is undefined whether s" is greater than, or less than s,
   though it is known that s" is not equal to s.

4.3. Corollary 3

   If s" from the previous corollary is further incremented, then there
   is no longer any known relationship between the result and s.

4.4. Corollary 4

   If in corollary 2 the value (n + m) is such that addition of the sum
   to sequence number s would produce a defined result, then corollary 1

   applies, and s" is known to be greater than s.

5. Examples

5.1. A trivial example

   The simplest meaningful serial number space has SERIAL_BITS == 2.  In

   this space, the integers that make up the serial number space are 0,
