They’re almost definitely A or I. Count how many times each symbol appears in the puzzle. The most frequent symbol is probably E. It could also be T, A, or O, especially if the cryptogram is fairly short. WebThe following formula tells us how to find P -1 given P: where d × d -1 = 1 (mod 26), and adj (P) is the adjugate matrix of P. The determinant of the matrix we are inverting is ac - bd (mod 26) = 15*19 - 12*2 = 261 = 1 (mod 26). We also need to find the inverse of the determinant (1), which luckily in this case is 1 because 1 is its own inverse. orchard view serious care review 2011
