Jason's p156, or 92P156, is a large symmetrical oscillator found by Jason Summers on October 28, 2004 in a RandomAgar search.[1] It is actually an eight-barrelled period-156 glider gun (firing four close glider pairs) that is currently the smallest known at that period,[2] with all output gliders suppressed by eater 1s. In the infobox all of the eater 1s are as close to the center as possible.

The population can be reduced at the cost of doubling the period, by replacing each eater with a snake, or by replacing each pair of eaters with a beehive to produce 60P312. The pair of gliders can also be caught by a pond or loaf in a boat-bit reaction (which only works if both gliders are present.) This paired boat-bit reaction is found in many of the 92p156-based gun variants recorded in Catagolue.[3]
