Prime after prime!

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

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

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

Department 8 - 5 years, 6 months ago

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

Surya Prakash - 5 years, 6 months ago

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

Do give it a try :)

Aditya Kumar - 5 years, 6 months ago

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

Marco Antonio - 5 years, 6 months ago

$23$

Akshat Sharda - 5 years, 6 months ago

Something bigger?

Aditya Kumar - 5 years, 6 months ago

$29\ddot \smile$

Akshat Sharda - 5 years, 6 months ago

@Akshat Sharda – Read the note carefully!
