True period 24 gun is a true period 24 gun discovered by Noam D. Elkies in 1997.[1] It uses four large period 4 oscillators (two of them variants of fountain, the other two adjoined by common casing) to hassle two T-tetrominos, which react together to produce gliders.
The form on the right is a reduced variant found by Karel Suhajda.[2]
