On reconstruction of binary codes by dimensions of their subcodes

It is proved that if there is a bijection between two binary codes that preserves dimensions of their subcodes with even cardinality, then the codes are equivalent. It is shown that this theorem is unimprovable.
Bibliogr. 9.

Keywords: binary code, strong isometry, reconstruction, equivalent codes.
