A for all is a period-6 oscillator found by Dean Hickerson on March 6, 1993.[1] Its claimed 13-glider synthesis was found by David Buckingham in 1993, but was forgotten about and not revealed until August 1995. This synthesis was later found to be invalid due to gliders crossing paths and replaced with a similar 12-glider synthesis which avoids this issue.[2]
