start: (0,0)

(3x+0,y)   --> (4x+4,y+1)
(3x+1,y+1) --> (4x+5,y+2)
(3x+2,y)   --> (4x+8,max(0,y-1))

(3x+1,0)   --> halt

(x,y) := 0^inf 110 <B 11011 01^x 011^y 0^inf
</pre>After simulating the map for 10^6 steps, x was ~10^124940, while y = 331762. This biased pseudo-random walk did not get lucky and recross the origin early in its trajectory.
