where
This supplement contains the two tables described in § 3 and two extra tables for references.
Table 1
contains a list of
all quintuples where
is the minimal polynomial of a Salem number 
of degree 6 and
. The preperiod m and period p of the
beta expansion for 
are listed in Table 1 if they satisfy m < 10000 and
p < 10000.
Table 2
contains a list of 
for 
provided
. This includes 18 values for which only a lower bound on D =
m+p is known.
Table 3 contains periods and preperiods m < 1000, p < 1000 up to trace 15.
Table 4 contains large periods for trace at most 15.
