with Sage 6.0 and the following program:
{{{
def search(p):
R = RealField(p)
m = 2^(2*p)+2^(p+1)-1
l = []
for a in range(2^p):
for b in range(2^p):
for e in range(2):
l.append(a*b*2^e)
l = uniq(l)
l.sort()
n = len(l)
i = j = 0
while i < n and l[i]-l[j] < m:
i += 1
sol = 0
while i < n:
if l[i]-l[j]==m:
sol += 1
j += 1
while i < n and l[i]-l[j] < m:
i += 1
print "sol=", sol
}}}
I get:
{{{
