Gotts dots (or 41 dots[1]) is a 41-cell pattern that exhibits O(t ln(t)) growth. It was found by Bill Gosper in March 2006 and helped lead to the construction of the 26-cell quadratic growth pattern.[2]
Collisions within the pattern cause it to sprout its nthswitch engine at generation t ~ 224n-6. The first switch engine appears roughly 220,000 generations in, and the second 3.6 trillion.
