%N a(3)(baseN) = least number m such that the quotient m/3 is obtained merely by shifting the leftmost digit (MSD) of m to the right end (LSD), and the multiple 3m by shifting the LSD of m to the MSD, in order of increasing number base, N.
%C 1001b2, 10b3 and 51b7 do not triple by specified shift and are not included although they allow MSD>LSD shift to make m/3. No 2digit number qualifies because the shift is an exchange (e.g., 51b7/3=15b7). 2076b11 is the highest order number of this type to be represented without letter digits.
