Goormaghtigh conjecture
WebWikipedia, Goormaghtigh conjecture; EXAMPLE: a(1)=1 is a repunit in every base. a(2)=31 is a repunit in bases 1, 2, 5 and 30. a(3)=8191 is a repunit in bases 1, 2, 90 and 8190. 31 and 8191 are Brazilian numbers in two different bases: 31 = 11111_2 = 111_5, 8191 = 1111111111111_2 = 111_90.
