Oops, Conjecture 5 should read,

CONJECTURE 5. J_N has characteristic polynomial of the form
p_N(x)=sum[v=0..n, c_(n,v)*t^(n-v)], where the c_(n,v) are given by the
triangle beginning as

{c_(n,v)}=
{1};
{1,-1};
{1,-5,5};
{1,-14,49,-49};
{1,-30,243,-729,729};
etc.,

with the absolute values of the outer diagonal terms yielding the sequence,
for r=0,1,...,

A52750={(2*r+1)^(r-1)}={1,1,5,49,729,...}.
