  We find bounds for the length of the systole -- the shortest essential,
non-peripheral closed curve -- for arithmetic punctured spheres with $n$ cusps,
for $n=4$ through $n=12$, some of which were previously known due to Schmutz.
This is shown using a correspondence between such surfaces and planar
triangulations. We show that for $n=7,10,11$, arithmetic surfaces do not
achieve the maximal systole length.
