Rotor segments are subsets of a rotor that can be attached to each other to create larger, more complicated rotors. The simpliest such rotor segment is the barber pole, a four bit rotor which has two attachment points on opposite sides. By attaching multiple segments together, a rotor of any length can be created. For simplicity, instead of showing all the individual segments and their attachment points, only the end attachments will be show, and the whole roter will be refered to as an order-n barberpole.

To create an oscillator from rotor segments, all attachment points must be either connected to a terminator segment, or somehow attached to another segment, creating a loop. The simpliest terminator for the barberpole is a group of three cells called a pre-block.

The first oscillator that can be created from a barberpole segement is the Bipole [8P2.1]. It consists of an order-1 barberpole terminated by preblocks at each end. Using an order-2 barberpole results in the Tripole [8P2.1], while and order-3 gives the Quadpole [10P2.1].

It's also possible to attach frame cells to barberpole based oscillators to greater larger, trivially different objects.

Terminal Segments

The pre-block is not the only possible terminal end for a barberpole. There are a number of casing variants. The first line shows some stable variants. The shows some Beacon [6P2.1] type oscillators are a part of the terminator, but the zones of influence don't overlap. The next two lines show several terminators where the beacon rotors do have some overlap with the barberpole's zone of influence. This means that they are considered to be a single rotor, but only in a trivial sense. The last line shows several rotors where the oscillators play a direct part in terminating the barberpole.

For the purposes of these discussions, all of these variations are considered to be equivalent to the pre-block terminator

Barberpoles can also be terminated by other rotors, as illustrated. Note that a number of these terminating segments, while considered a unit for barberpoles, can be decomposed futher when other segment types are considered. They can also have attachment points for other wick segment types. For example, for the lemon, there is a two cell attach point shown in yellow.
