3, 2, 7, 6, 5, 308, 51, 34217, 8131871 (list; graph; refs; listen; history; internal format)

	OFFSET	`1,1`
	COMMENTS	`Not defined for n>9.`
	EXAMPLE	`a(1)=3 since 3 in base 1 ('unary') is 111 and 111 can be divided by 3. a(3)=7 since 7 in base 3 is 21 and 21 can be divided by 3. Trivial solutions (m<n) do not count.`
