Couldn't understand what the symbol P^ (P cap ) means in Q5.1 (b) here: http://ocw.mit.edu/courses/mathematics/18-06sc-linear-algebra-fall-2011/ax-b-and-the-four-subspaces/transposes-permutations-vector-spaces/MIT18_06SCF11_Ses1.5sol.pdf Further can't understand the solution: what's the block diagonal matrix? Can't we just use the matrix in 5.1 (a) problem because P^4 = I*P = P not equal to I which is what we need?
