Eleven loop

Eleven loop (or 11-loop, or long loop, or very long hat) is an 11-bit still life.

Commonness

Eleven loop is the seventy-first most common still life in Achim Flammenkamp's census, being less common than long integral but more common than claw with tail.[1] It is also the eighty-third most common object on Adam P. Goucher's Catagolue.[2]

Synthesis

On April 17, 2007 Dean Hickerson found a 4-glider synthesis of this still life.[3]

gollark: ++exec```luafunction factorial(x)local a = 1for i = 1, x do a = a * iendreturn aendfunction scream(x, a, b)if a == 0 thenif b == 0 thenreturn factorial(x) + 1else return math.pow(factorial(x), scream(factorial(x), 0, b - 1))endendlocal g = factorial(scream(x, a - 1, b))return math.pow(g, g) endprint(scream(5, 2, 2))```
