11111 Repunit           Discovered 1995 Nov. 16 by T. Kobayashi at Oizumi.
A repunit ("repeated unity") is a number consisting solely of the digit 1. The name was introduced by Albert H. Beiler in his book Recreations in the Theory of Numbers (1964). For this minor planet, the name was suggested by J. Meeus.
