COMMENTS
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 2-digit 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.
