On the Subject of S.E.T.

Modules based on card games seem to be a thing now.

• The module presents a keypad with mysterious symbols.
• A S.E.T. (Strangely Elusive Triplet) is a set of three symbols that satisfies all four of the following conditions:
  • The symbols have the same shading or all different shadings (filled, wavy-patterned and empty).
  • The symbols have the same quantity of dots or all different quantities of dots (0, 1 and 2).
  • The symbols can be found in all the same row or all different rows in Table 1.
  • The symbols can be found in all the same column or all different columns in Table 1.
• The symbols on the keypad contain a single S.E.T. consisting of three symbols. Press those symbols (in no particular order).
