Big S (or large S[1] or S-spiral[2] or simply S[3]) is a simple 14-cell still life discovered by the MIT group in 1971.[4] It is produced by colliding a pi-heptomino with a boat.
Commonness
Big S is the twenty-second most common still life in Achim Flammenkamp's census, being less common than snake but more common than bi-pond.[5] It is also the twenty-nineth most common object on Adam P. Goucher's Catagolue.[6]
