Proper distinguishing arc-colourings of symmetric digraphs

作者：

Highlights：

• Page 2, Line -7. There is an extra comma in ‘Ai, i = 1,..., 4,.’.

• Page 2, Line -5. “A” should be changed to “A”, for example, “proper”, “without monochromatic digraph Ai”.

• Page 6, Line -12. It will be better to add a comma after the formula.
