%N Sum of digits of n in fractional base 7/6.
%C The base 7/6 expansion is unique and thus the sum of digits function is well-defined.
%e In base 7/6 the number 7 is represented by 60 and so a(7)=6+0=6.
%o (Sage) # uses [basepqsum from A245355]
%o [basepqsum(7,6,y) for y in [0..200]]
%Y Cf. A024643, A007953, A053828.
