Sawtooth 262 is a diagonal sawtooth that was discovered by David Bell on July 9, 2005. It is currently the smallest sawtooth in the sense that its minimum repeating population of 262 is the least of any known sawtooth.

The pattern works by using 180-degree glider reflections from the 136-cell version of the 4-engine Cordership. A single figure eight reflector is used to delete two outbound gliders with each returning glider.

Original form

The original form of this sawtooth was discovered on July 7, 2005. It used the slightly larger 3-engine Cordership at its top-left, and two figure eights instead of one figure eight, eater 1, boat and block for glider deletion. It had a minimum repeating population of 269.
