COMMENTS

This is to 6 as A176763 is to 3 and as A030001 is to 2.

LINKS

Table of n, a(n) for n=1..21.

FORMULA

a(n) = MIN{A000400(i) such that n in decimal representation is a substring of A000400(i)}.

a(n) = 6^A062523(n). - Michel Marcus, Sep 30 2014

EXAMPLE

a(1) = 1 because 6^0 = 1 has "1" as a substring (not a proper substring, though).

a(2) = 216 because 6^3 = 216 has "2" as a substring.

a(3) = 36 because 6^2 = 36 has "3" as a substring.

CROSSREFS
