coolest function

Probably unsolveable.

Agreed. No real starting point. A lot of guess work just to find a starting point!

What´s that!?!?!
I can read: F(X) = { and below R/Q but nothing else...

SPOILER:
C1/r5-9 => write F(X) = (the "equal" sign is in C12-13/r6,8)
C11/r15-19 => write R, diagonal from C14/r19 to C19/r14
C20/r15-19 => write Q, there are dots in C23,25/r19
And now the tricky part...
C15/r2-6,r8-12
C16/r1,r13
C17/r3-6,r10,r12,r19
C18/r3,r6,r8,r10,r13
C19/r3-6,r10,r12,r14.

Wow, Joe Tramp. I have no idea how you managed to figure this one out. Couldn't complete it without ALL of your hints though. Thanks!

I would ban this moron Bellowe. He made 3 math puzzles already all unsolvable only using logic. Thanks Joe Tramo, wouldn't have made it without your help but there is a mistake. C17/r3-6,r10,r12,r14,r16.

Looks like a bunch of scribbles.

Thank you.
