Consider the following sentence: what is its truth value?

1)	li vo na'e sumji li re li re

On the "na'e entails na" view, this means "4 is not the sum of 2 and 2"
and is false.  On the other (and/djan) view, it means "4 is a non-sum
of 2 and 2" and is true, since 4 is a product (which is not a sum)
of 2 and 2.

On the other hand,

2)	na'ebo li vo sumji li re li re
	Other than 4 is the sum of 2 and 2

is false on any view, and likewise if you move the "na'ebo" to
any of the other sumti.
