Simplex's Fixation

"8 was sent, 4 of them have shown theirs immaturity."
--Mr. XYZ

There are group and then there was grouping.

Hint: Well, since I am 26 years old I technically have the right to be "immature." He is claiming that he can group things without know that they are; that is, even withou the use of probability or not. For example, say you have a family of group (a set that is equip with a binary operation with certain property) can you tell what in these sets and group them accordingly?
