In 1989 Hickerson created the first oscillator search program with which he found many small, low-period oscillators, such as caterer, Monogram, and fumarole. He has since found many sparkers as well as billiard tables, including the first known period-17 oscillators.
Hickerson also used automated searches to discover the first spaceships other than the glider and the various speed c/2 orthogonal spaceships; these new spaceships traveled at speeds c/3, c/4, and 2c/5. In addition to these, he discovered the first diagonal c/4 spaceship other than the glider, as well as the first period 2 spaceships. He again advanced spaceship technology when, in 1991, he successfully combined thirteen switch engines to create the first c/12 diagonal spaceship, the 13-engine Cordership.
