You and Aarex don't seem to understand that examples do not constitute a satisfactory definition of anything, especially in a mathematical context. Didn't Socrates already point this out 2400 years ago when he ridiculed the circularity of the definition of "piety". (Since you probably don't understand the reference you can read everything you need to know here ) Of particular importance here is Euthyphro's first definition of piety. He provides only a single example of something pious. This answer does not satisfy Socrates who wants a definition which can be used to determine what is and what is not pious. ie. He needs a decision algorithm.
