Did you notice the puzzle number Ripper? The clashes are either anagrams of a related number or a representation of the same number using Roman numerals. You'll know what geometric shape represents the mathematical process to make the 4 clashes equal the puzzle number.
If it's a matter of working out the two instructions from the 30 clues (which is a bit of a faff) then remember to skip acrosses 8,11,34+35 and downs 2,9,21+27. The letter counts for the two instructions are -
3,4,3 and 7,4,4,5.
But if you've really had enough of it, i hope you're enjoying the sunshine at last!
