%C A256306 Base 6 variant of A256078 (base 2) and A048379 (base 10). See A256303 - A256308 for bases 3 through 8, A256289 for base 9, and A256296 for the variant where the result is converted back to base 10.
%e A256306 a(6) = 21 because 6 = "10" (in base 6) becomes "21".
%e A256306 a(35) = 0 because 35 = "55" (in base 6) becomes "00".
