From a semitrimagic square of order 12 with 3 pairs of possible diagonals
we can derive three essentially different trimagic squares.

From a semitrimagic square of order 12 with two specially arranged pairs of possible diagonals
we can obtain two axially symmetric and two nonsymmetric trimagic squares.
