We give a complete list of the groups of order 3^8. The groups
are given by their SmallGroup codes, which are understood by both
GAP and Magma. If c is the code for one of the groups, then to obtain
the corresponding group in Magma enter SmallGroupDecoding(c,3^8) and
in GAP enter PcGroupCode(c,3^8).
The codes are given in a set of files, each file of the same form.
For example the file "rank7class2" contains the codes for the ten
seven generator groups of class two and order 3^8. The codes are
given as a sequence "codes":
There are 22 files in all, each of the form "rankmclassn",
where m is the rank of G/(G^3.[G,G]) and n is the p-class of G.
(The classification of finite p-groups uses the lower exponent p
central series
G = G_1 > G_2 > G_3 > ... > G_n > G_{n+1} = {1},
where, for i > 1, G_i = G_{i-1}^3.[G_{i-1},G].)
The number of groups of rank m and class n is given below
as the n-th entry in the m-th row.
