%N Records for the number of 'Reverse and Add' steps in base 2 needed for a Lychrel number to join the trajectory of a smaller Lychrel number (i.e., its seed). Record setting numbers in A306481.
%C Record setting numbers in A306481.
%C Similar to the number of steps needed to reach a palindrome in the Reverse and Add! trajectories (see A066144 and A066145), the number of steps needed for a Lychrel number to reach the trajectory of its seed is relatively small.
%C Lychrel numbers in A066059; seeds in A075252 (for base 2).
%Y Cf. A066059, A066144, A066145, A075252, A306481.
