Can the Complete Graph on ten vertices be edge covered by three copies of the Petersen Graph?

Put an additional means Colour the sides of the full chart with 3 colours, to make sure that 3 subgraphs are each a duplicate of the Petersen Graph. I listened to someplace that it can be done (Maybe I need to not take place MathOverFlow!) yet I have actually invested all weekend break attempting and also have actually encouraged myself it is difficult. Many thanks beforehand for your remarks.
