Consider the set [0, 1], and consider it's partition A=(0,14,12,34,1) and consider a refinement of this partition, B Note that refinement of a partition A contains all points of A and possibly some other points, thus B can be considered as: B=(0,18,14,12,34,78,1) Here it can be seen that A is contained in B, i.e. A sub B And if we consider another refinement of A: B1=(0,18,14,38,12,34,1), again note that A sub B1 i.e. B1
is an refinement of A but BB1 sub B1 is not an refinement of B.
