%N In base 3: n sets a new record for the number of Reverse and Add! steps needed to reach a palindrome starting with n.
%C RECORDS transform of A077402. - Base-3 analog of A066144 (base 2), A075686 (base 4) and A065198 (base 10). Integers like 103, for which a palindrome is (presumably) never reached (cf. A077404), are of course disregarded. A077407 gives the corresponding records.

%e Starting with 15, 3 Reverse and Add! steps are needed to reach a palindrome; starting with n < 15, less (at most 2) steps are needed.
%Y Cf. A065198, A066144, A075686, A077402, A077404, A077407.
