Prime after prime!

I found this somewhere. I thought of sharing with everyone. Do try finding out numbers of such kind! (bigger than this)

Next largest such prime is \(59393339\). There are only \(83\) such right-truncatable primes.

Sir did you proved it or searched it internet

I've heard of this before, so I just looked up Truncatable Primes. But I don't think it's particularly difficult to prove that there's only a limited number, so that a quick computer search can find all of them.

@Michael Mendrin Oh, can you suggest me some ways to do my RMO well

I think it is difficult to calculate that without using coding.

I think one can get such primes by coding. If its a number theory problem , its way too difficult for me...

This is so far from me. Maybe one day, but not today.
