you have a grid of 8 squares 1 on top 3 on next line then on on next line then 1 on bottom you have letters abcdefgh try and fit them into grid so that no consecutive letters touch
The formatting didn't come out right. Assuming the single squares on the top and bottom rows are directly above / below the middle square of the second and third rows then the above solution should look like this (where x represents the blank squares in the grid)
x g x
d a c
f h e
x b x
Or...... xCx
GAF
EHD
xBx
And I'm shure there are other solutions. It becomes very easy if you put the letters A and H in the centre that way they will be the only ones to have contact with 3 other letters and seeing as they are the first and last letters of the squence there is only one prohibited letter for each, instead ou two like all the other letters in the sequence. Then just go from there.
