Gianni,
How does one interpret the notation? Specifically, the cell designation followed by a hyphen and a number, such as r2c2-7? Below is an XY-Chain written in Eureka notation.
(4=5)r2c7-(5=7)r2c2-(7=4)r2c1-(4=6)r7c1 (6=9)r7c4-(9=7)r5c4-(7=4)r1c4=> -4r1c79
Here is a shorter way to write it: (4=5)r2c7-(5=74)r2c21-(4=69)r7c14-(9=74)r51c4=> -4r1c79 |

Hi Marty,
I don't know the Eureka notation well and I used an indication that i think simple:
r2c7 is connected to r2c2 with number 5,
r2c2 is connected to r2c1 with number 7 and so on.
I promise that next time I will try to use the examples you gave me, but they are so looooooooooong 
Ciao Gianni |

Gianni,
Use whatever you're comfortable with. If you should have any questions about Eureka, just ask, I'd be willing to help. |
