Runny nose is a period-3 oscillator found by 83bismuth38 on 5 March 2017.[1] It is notable due to its small size, at 21 cells, which surprised many due to it not being found earlier.
As such, it filled in a few gaps in oscillator collections: runny nose is technically the first example of a p3 pipsquirter, as well as the smallest pipsquirter of any period. However, due to a lack of clearance, it is not particularly useful in this regard.[2]
Tanner Jacobi and iNoMed found an 18-glider synthesis of this oscillator on July 26, 2021.[3] iNoMed reduced this to 17 gliders on October 4.[4] On January 29, 2024, KtT lowered the cost to 16 gliders,[5][6] followed by a 14-glider synthesis by Goldtiger997 on January 30, 2024.[7][8]
