Making a right mess of this after a speedy grid fill. I have four of the elements but am hampered by not being sure from the superfluous letters if there are 4 superfluous letters in the first element 9 on the next, or if it's 5/8. If it's the latter, then elements 1 and 2 are related, but there can't be an extra letter in 14 to make what I want to make it . Also there are so many element 4s in the area that you don't know where to start. Also does symmetrical mean in themselves or in the grid.....
