Grin reagent^{[please clarify name]} is a catalyst that is extremely sensitive to a grin, and will react to it to create another grin. This allows a p12 oscillator to be made:

This can also be achieved with the eater bridge eater, but its fast recovery time disallow a P12 oscillator, and also disallow period multiplying (e.g. the 65P48 weld).
