10000...00001 (6867-digits)

This number is a probable-prime (likely to be a prime but we have not (re-)proven it on this site).

This 6,867-digit number is the largest known trinomial emirp of the form 10^x + c·10^y + k. Discovered by Yuri Ganda (Project LEVIATA) in April 2026, it is part of a catalog of 268 such emirps. Both this number and its decimal reverse are probable primes (Miller‑Rabin, error < 4^-25). ECPP certification via PARI/GP and Primo has been completed.
