%N A061932 Numbers n such that n divides the (right) concatenation of all numbers <= n written in base 3 (most significant digit on right, least significant zeros not written).
%C A061932 This sequence differs from A029496 in that all least significant zeros are removed before concatenation.
%C A061932 No more terms < 10^7. [_Lars Blomberg_, Oct 17 2011]
