theorem Th10: :: NBVECTSP:10

for m, n being non zero Element of NAT
for A being FinSequence of n -tuples_on BOOLEAN
for B being finite Subset of (n -BinaryVectSp) st rng A = B & m <= n & len A = m & A is one-to-one & ( for i, j being Nat st i in Seg n & j in Seg m holds
( ( i = j implies (A . i) . j = TRUE ) & ( i <> j implies (A . i) . j = FALSE ) ) ) holds
B is linearly-independent
