What is the longest notation? (4PC edition)

There is a forum on chess.com called what is the longest notation? and thought of doing it here in this club since 4pc has different notation. This is what I think is the longest notation:

          When you take the blue sergeant the notation αxὂh7=K+++### is a whopping 13 characters long!! the axoh7 is because there are 2 other pieces the sergeant can take so it makes it specifically tells the sergeant captures on h7. the = K is of course because of promotion to King and the +++### come from after promoting to the king, you check all the other royal pieces and at the same time mate them because it is koth. By the way if you wonder how none of pieces are not in check, well i just put ctk so there are no checks. If you know a notation with 14 or more characters put it here. I do think this is the longest one possible. Try out this position for proof of the notation!

also it is not aXo it is another sergeant that captures. sorry for the mistake in picture. it is not a red berolina it is a red sergeant

it is oXo

interesting

If you turn on enhanced notation in the settings, it's even longer.

γi10xδh11=Q+++###

17 characters!!

i have two more than ChessMasterGS

The strategy is to capture and checkmate at the top of the board so there are two number to name the case where there are the capture. If we capture at the center, there are only one number  to name the case where there are the capture. That's how i did to make a notation with two characters more! 

Who can beat my record of 17 charaters?
