We can number the coins, just to make the movement easier to follow, and we
start with this structure:
1 2 3
7 8
4 5 6
We can move coins 4, 5, 6, 7 around to the end of the top line to end up
with:
1 2 3 4 5 6 7
8
And we now have four rows of four coins each: 1-4, 2-5, 3-6, and 4-7!
Cheers, and ais523, thanks for the extra points ;-)
