  The Holographic Space-time (HST) model of inflation has a potential
explanation for dark matter as tiny primordial black holes. Motivated by a
recent paper of Barrau\cite{barrau} we propose a version of this model where
some of the Inflationary Black Holes (IBHs), whose decay gives rise to the Hot
Big Bang, carry the smallest value of a discrete symmetry charge. The fraction
$f$ of IBHs carrying this charge is difficult to estimate from first
principles, but we fix it by requiring that the crossover between radiation and
matter domination occurs at the correct temperature $T_{eq} \sim 1 eV =
10^{-28} M_P$. The fraction is small, $f \sim 2\times 10^{-9}$ so we believe
this gives an extremely plausible model of dark matter.
