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.
