Baker's dozen is a period 12 oscillator consisting of a loaf hassled by two blocks and two caterers. The original form (using period 4 and period 6 oscillators to do the hassling) was found by Robert Wainwright in August 1989. Its population is three baker's dozen cells.

By rephasing and moving the caterers, it is possible to get a 37-cell variant. Using mazings would also work.

It can be stabilised and welded in many ways. A caterer can be used in 2 ways, one way is also suitable for the jam. A mazing would work, and two can be stabilised next to each other. 2 opposite ones can be stabilised with 2 bookends (shown as bookend on snake) in the lifeviewer.
