A159547 Smallest number b such that the number whose digits are n in base b is a skinny number 0
2, 5, 10, 17, 26, 37, 50, 65, 82, 2, 3, 5, 10, 17 (list; graph; refs; listen; history; text; internal format)

LINKS

Table of n, a(n) for n=1..14.

FORMULA

a(n) <= 10 iff n is in A061909

EXAMPLE

a(10) = 2 because 10^2 = 100 in all bases >= 2. a(14) = 17 because in base 16, 14^2 is 1|9|0 while in base 17 14^2 is 1|8|16 (where numbers separated by |'s represent individual digits, whereas digits with no | in between stand for a single digit in bases greater than 10.
