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.

I think it is difficult to calculate that without using coding. – Surya Prakash · 10 months, 1 week ago

I think one can get such primes by coding. If its a number theory problem , its way too difficult for me... – Nihar Mahajan · 10 months, 1 week ago
