A088916 Triangular array read by rows, 2<=k<=n: T(n,k) = smallest number that in base k representation is not contained in n^n. 0
3, 4, 2, 3, 2, 2, 7, 8, 2, 2, 7, 4, 5, 0, 2, 10, 3, 5, 4, 0, 2, 3, 7, 2, 0, 0, 0, 2, 13, 2, 6, 0, 7, 7, 3, 2, 13, 4, 6, 2, 0, 3, 3, 0, 2, 17, 10, 8, 5, 4, 3, 0, 4, 4, 2, 9, 7, 5, 7, 1, 4, 3, 2, 3 (list; table; graph; refs; listen; history; text; internal format)

COMMENTS

T(n,n) = 2 for n>2.

LINKS

Table of n, a(n) for n=2..65.

EXAMPLE

Initial values of n^n in representations with increasing base:

2^2: ........................... 100

3^3: ....................... 11011 1000

4^4: ................. 100000000 100111 10000

5^5: ......... 110000110101 11021202 300311 100000

6^6: 1011011001000000 2101000000 23121000 2443111 1000000

'11021202' = ternary 5^5: all ternary numbers < 8 are contained

in '11021202': '0', '1', '2', '10', '11', '12', '20' and '21', but not

8='22', therefore T(5,3)=8.
