There should be several smaller solutions. My example was intended to be small but informative. Tiny solutions make poor examples because everything tends to fold in on itself. I would expect the smallest solution to come from setting h=0. That leads to the choices

x=2 (it must be a factor of 2h-h+1=2)
k=1 (k and q must be factors of 2x-1=3)
y=1
z=2
q=3
m=2
r=1
p=1

For the tiny solution p=1, q=3, r=1, and the equation become 4=4.

Now for a reverse challenge - how many solutions can you find between this tiny solution and my example?
