But can you do it? :-)

I think it's an obvious follow-up question. It's not as hard as finding the highest prime. Each step is simple.
We can even draw nice graphs like the Collatz conjecture.

I don't think I can do this....
Last time to find the highest left truncatable prime is near my hardware's memory limit, This number is for sure larger than that one
but I will try from tmr :)
