Worker bee (or lonely bee[1]) is a period-9 oscillator and was found by David Buckingham in 1972.[2][3] It consists of four eater 1s hassling a row of 6 live cells, which by itself is a dying spark that a lone table also converges to.
Similar to the snacker, the worker bee is extensible - it is, in fact, a finite version of the infinite one-cell-thick oscillator consisting of alternating groups of six ON cells and two OFF cells.
This oscillator first appeared semi-naturally in April 2015, in a symmetric soup submitted to Catagolue by Dave Greene.[4]
In other rules
In other Life-like rules with transition S8, for instance EightLife, the core of worker bee evolves into a honeycomb, making the still life more common than that in regular Life.
By removing the isotropic non-totalistic transition B3r, the worker bee needs no external support. A row of 6 cells becomes a small period-9 pipsquirter.
