If C is a binary linear code, one may choose a subset S of C, and form a ne
w code C-S(T) which is the row space of the matrix having the elements of S
as its columns. One way of picking S is to choose a subgroup H of Aut (C)
and let S be some H-stable subset of C. Using (primarily) this method for p
icking S, we obtain codes with record-breaking parameters [92,8,44], [105;8
,50], [108,8,52], [79,9,36], [123,9,58], [130,9,62], [175,9,84], [242,9,118
]: and [245,9,120].
