COMMENTS
| Also: a(1) = 0; a(n) = Min{x integer | x > a(n-1) and all digits to base 10 are distinct}.
a is finite: a(8877690) = 9876543210 is the last term; a(8877689) = 9876543201. The largest gap between two consecutive terms before a(250000) = 2409653 is 104691, as a(175290) = 1098765, a(175291) = 1203456. - Reinhard Zumkeller (reinhard.zumkeller(AT)gmail.com), Jun 23 2001
Complement of A109303. - David Wasserman (dwasserm(AT)earthlink.net), May 21 2008
