134P25 is an unnamed period25 oscillator. It was the first period 25 oscillator to be found,^{[1]} and was discovered by Noam Elkies on September 23, 1994. In its original form it used toasters instead of eater 1s.
It works by using two middleweight volcanos to push two Ttetrominoes three cells in 14 generations and then back in 11 generations.
A similar reaction is employed in the current smallest period20 glider gun, albeit where a middleweight volcano hassles a Ttetromino three iterations after its appearance, that becomes a traffic light predecessor in thirteen more, and in the Tnosed p20.
