The Egyptian walk is a 12-cell still life.
Among the 121 still lifes with 12 cells, this is the 114th most common (i.e. 8th rarest) still life according to Catagolue.
A 6-glider synthesis of this still life was found by Chris Cain on March 13, 2015 based on a suggested predecessor from Matthias Merzenich.[1]
