EXAMPLE

a(12) = 4: the distinct numbers formed by the digits of 12 are 1, 2, 12, 21. The geometric mean of these numbers is 504^(1/4)=4.73813722053758678534150735741308... and the integer part is 4.

EXAMPLE

The digits of 13 can form 1, 3, 13 and 31. The digits of 201 can form 0, 1, 2, 10, 12, 20, 21, 102, 120, 210 and 201. Thus a(13) = 4, a(201) = 11.
