Siamese is a term used in naming certain still lifes (and the stator of certain oscillators). It indicates that the object consists of two smaller objects joined in such a way that they share two or more cells. (Still lifes sharing a single live cell are not possible: any shared live cell needs to have at least 2 neighbors within one half for stability, which would put it at 4 or more neighbors when joined up.) Examples include carrier siamese carrier, carrier siamese snake, snake siamese snake, loaf siamese barge and elevener.
