COMMENTS

This is to 11 as A176763 is to 3 and as A030001 is to 2.

LINKS

Table of n, a(n) for n=1..24.

FORMULA

a(n) = MIN{A001020(i) such that n in decimal representation is a substring of A001020(i)}.

EXAMPLE

a(1) = 1 because 11^0 = 1 has "1" as a substring (not a proper substring, though).

a(2) = 121 because 11^2 = 121 has "2" as a substring.

a(3) = 1331 because 11^3 = 1331 has "3" as a substring.

CROSSREFS

Cf. A001018, A030001, A176763, A176764-A176773.
