A concatenation construction for propelinear perfect codes from regular subgroups of GA(r,2)
A code C is called propelinear if there is a subgroup of Aut(C) of order |C| acting transitively on the codewords of C. In the paper new propelinear perfect binary codes of any admissible length more than 7 are obtained by a particular case of the concatenation construction-1981 [21] and the regular subgroups of the general affine group of the vector space over GF(2).
