Iconic Kitchener Trios emerge when the three individuals compliment each other's faces in every pairing of the three. For this to be possible, two of the three individuals must have three face lines and the other one must have two. The individual with two face lines must be able to follow the equation for 'Great Looking Duos' with both of the other trio members.

AB + ACD

Meanwhile, both trio members with three face lines must be able to follow the equation for 'Good Looking Duos'.

A second version of the iconic trio comes about when all three characters have three face lines and each character pair fits the equation for 'Good Looking Duos'. This can manifest in two variations. 

ABC + ABD + ABE

ABC + ABD + ACD

​

When either version of these parameters are met, we have a cohesive looking unit of three who compliment each other as a group and in every pairing - making for an iconic trio.
