p60 B-heptomino hassler is a period-60 oscillator found by Jason Summers and Noam Elkies in July 2003.[1] It consists of four unices hassling two B-heptominoes.

The active region on the "inbound" path is the R-turner without its first blinker.

In August 2023, Mitchell Riley found smaller supports for the hassler using tubs and killer toads.[2] On August 12, 2023, Chris857 found a 22-glider synthesis of this form.[3][4]
