− | *The TP Cost increments with each usage, according to the tetrahedral formula: TP Cost = ((n)(n+1)(n+2))/6, for the nth use of the dice each day. The sequence of TP Cost is as follows: 1, 4, 10, 20, 35, 56, 84, 120, 165, 220, 286, 364, 455. | + | *The TP Cost increments with each usage, according to the tetrahedral formula: TP Cost = ((n)(n+1)(n+2))/6, for the nth use of the dice each day.
