Mark Niemiec has found some new ways to construct a Bipole [8P2.1]
in place from an Aircraft Carrier [6.3] that uses fewer Gliders
that previously known methods. This allows, with one exception, the construction of all
known Period 2 Oscillators and Pseudo-Oscillators of 20 or fewer bits that contain a Bipole-type rotor.
He also found some methods that use an Integral [9.5], which
however, currently don't seem to have any uses.
