No.765 
No.765 by Anatoly Stepochkin – Tanagra s# with two variations in every phase! (JV)
Definitions:
Maximummer: Black must play the geometrically longest move or may choose from among longest moves of equal length, distances being measured from the center of each square. Diagonal and oblique distances are measured from the orthogonal coordinates by using Pythagora’s theorem (take the square root of the sum of the squares of the orthogonal distances). All other orthodox chess rules apply.
KoKo: A move is possible only if the piece moved arrives on a square next to another unit.
Grasshopper(G): Moves along Q-lines over another unit of either color to the square immediately beyond that unit. A capture may be made on arrival, but the hurdle is not affected.

These specific Köko mates are known before, but to get four of them into a single position is quite a good result – with the downside that the variations in the first solution are reflections of each other.
By chance I have published a few positions with 4 different such checkmates with the same material and the same stipulation (with exception of length), using various forms:
StrateGems 2004 – set + try + solution
Quartz 2004 – short set + 3 solutions
idee&form 2004 – short set + try + solution
harmonie 2009 – short set + 3 solutions
However, the AS’s position seems to be the most harmonious in my view.
