37P7.1 is a period-7 oscillator discovered by Scot Ellison in October, 2005. It provides a weak spark that can be used in the creation of higher period oscillators. It can be used in the p7 bumper to reduce the population but at the cost of a higher bounding box.

As a catalyst

37P7.1 can be used as a catalyst, like so:
