SWhat changed
Introduced a seven-multiplication 2-by-2 construction and recursive subcubic matrix multiplication, with related elimination consequences.
Scientific scope
The record is Strassen's sole-author 1969 paper and its arithmetic-operation model. It is not the current best matrix-multiplication exponent, a numerical-stability guarantee, or a lower bound.
