 A256293 Apply the transformation 0 -> 1 -> 2 -> 0 to the digits of n written in base 3, then convert back to base 10. 8

 OFFSET 0,2 COMMENTS Base 3 variant of A035327 (base 2) and A048379 (base 10). See A256294 - A256299 for bases 4 through 9, and A256303 for the variant where the result is not converted back to base 10. LINKS EXAMPLE a(3) = 7 because 3 = 10[3] becomes 21[3] = 7. a(8) = 0 because 8 = 22[3] becomes 00[3] = 0.
