 A245347 Sum of digits of n written in fractional base 8/3. 0
 0, 1, 2, 3, 4, 5, 6, 7, 3, 4, 5, 6, 7, 8, 9, 10, 6, 7, 8, 9, 10, 11, 12, 13, 4, 5, 6, 7, 8, 9, 10, 11, 7, 8, 9, 10, 11, 12, 13, 14, 10, 11, 12, 13, 14, 15, 16, 17, 8, 9, 10, 11, 12, 13, 14, 15, 11, 12, 13, 14, 15, 16, 17, 18, 4, 5, 6, 7, 8, 9, 10, 11, 7, 8, 9 (list; graph; refs; listen; history; text; internal format)
 OFFSET 0,3 COMMENTS The base 8/3 expansion is unique and thus the sum of digits function is well-defined. LINKS FORMULA a(n) = A007953(A053829(n)). EXAMPLE In base 8/3 the number 14 is represented by 36 and so a(14) = 3 + 6 = 9. PROG (Sage) # uses [basepqsum from A245355] [basepqsum(8, 3, w) for w in [0..200]] CROSSREFS Cf. A007953, A000120, A024645, A053829, A244040.
