Sentence examples for double products from inspiring English sources

If we expand M 2 = ( C k 1 + C k 2 + … + C k m ) 2, the double products contribute only even (~0) entries: M 2 = C 2 k 1 + C 2 k 2 + … + C 2 k m mod 2. If N = 2 n, squaring matrix M n-times gives M N = C N k 1 + C N k 2 + … + C N k m mod 2. Because C N k 1 = ( C N ) k 1, and C N = I (the unit matrix), M N = m·I mod 2. This proves the following.
