Agreed. This is also the most important use of the possibility
generator by far.

A possibility space depends on mathematical rules. A simple cellular
language could take care of unexpected configurations that an applitude
couldn't (without the applitude becoming overloaded with options).
The basic rules are the formulas for combinations and permutations:
P(n, r) = n!/(n-r)!
C(n, r) = n!/r!(n-r)! or C(n, r) = P(n, r)/r!
With permutations order matters, with combinations order doesn't matter.
Examples of possibility spaces:
-Painting of geometic shapes (ie how many unique ways could you color a
cube with two colors, answer -- 5)
-Chess, Go, other board games
-Number of ways to dress yourself with your wardrobe
-Number of different fruit punches you can make with ten different fruits
(you could likely find some rather odd combinations in the resulting list)
-Number of different playlists of your song collection you can make with
certain criteria you specify
A bigger idea than a possibility generator would be a mathematical problem
solver. This idea would be a MASSIVE undertaking. But it would allow
people to use mathematical concepts beyond their understanding, like
