"permutations are possibilities or paths....

ie for every pair of shoes you buy you get the choice of pumps/platforms/mary-janes/sandels/...

and for each of them you get to choose color red/green/blue/aqua/magenta/....

and for each color you get to choose shiny/mat

and for each shoe you also get to choose material leather/material

and if you choose leather you have to choose the type pig/cow/lizard/....

and then Cpt Sarcasto gets a headache trying to figure out how to write code to deal with all the types of shoes....

(and the girl just decides to try and buy one of each!)"
