do u mean that u forgot to draw the edge from 6 to 8??

and also, where is your vertex 0? 0 is an element of $\displaystyle Z_{14}$ right?

can anyone give me a hint on how to solve question 2a?

im a little confused i used Euler's formula and i got that the number of faces should be 9 which is clearly a lot less than it is in real life...is there any way i can work out the number of actual faces by looking at the graph? and also, where did u get the other formula from? and how do i calculate the number of edges in each region?
