Comments
A triple twist is defined as having three independent elements, each element being different.
A pair of spiral gauzes outside a solid core is a defined as double series. So it is NOT the number of elements that count but what the elements do, that dictates their classification.

A triple series occurs in approx. 1-300 ratio within the opaque twist stem classification.
