%N To calculate nth term, find all shortest common superstrings of the binary representations of all natural numbers from 1 to n, read them as numbers in base2, and pick max.
%e a(5)=52 because there are 2 shortest common superstrings of 1,10,11,100,101, they are 110100=52 and 101100=44. Pick 52 because 52>44.
