Repunit
In recreational mathematics, a repunit is a number like 11, 111, or 1111 that contains only the digit 1 — a more specific type of repdigit. The term stands for repeated unit and was coined in 1966 by in his book Recreations in the Theory of Numbers. A repunit prime is a repunit that is also a prime number. Primes that are repunits in base-2 are Mersenne primes.
