Comments

Using Max Alekseyev's PARI "Gen" program (see A010061), we run

vector(500,k,length(Gen(k,2))),

vector(500,k,length(Gen(k,4))), and

vector(500,k,length(Gen(k,6)))

to find the numbers that are generated in bases 2, 4, and 6, and then take the even numbers that are common to all three lists.
