Harbor is a period-5 oscillator that was found by David Buckingham on September 17, 1978.[1] It was named by Dean Hickerson. In one phase, it consists of four ships and eight boats.
A 35-glider synthesis of this oscillator can be found in jslife.[2] Forum user yootaa found a 23-glider synthesis on December 22, 2017.[3]
About 1 in 40000 odd-width eightfold symmetric soups (D8_1) form a harbor in the centre.
