p68 century hassler is a small period-68 oscillator found by Nico Brown on April 21, 2023. With only 38 cells, it is the smallest known period-68 oscillator by population; the former record was 71P68.

It emits V sparks and domino sparks. One example of its use as a V sparker, functionally a dot, is for a completion of this p68 B-heptomino hassler, where the partial was found by Noam Elkies in 1996 and appears in jslife. This oscillator was previously completed with a larger p68 long bun hassler as a sparker.
