The heptapole (or septapole) is the barberpole of length 7.
The first known appearance of the heptapole in a symmetric soup was on January 26, 2015, in a soup found by gameoflifeboy using apgsearch.[1] It first appeared naturally on December 11, 2018, in a haul submitted to Catagolue, making it the longest barberpole and the last 13-bit periodic object to have emerged naturally.[2]
