Can someone show me all the combinations possible with these things
A
B
X
Y
LB
RB
LT
RT
L
R
U
D
Does each have to be used once? Are the two-letter combinations supposed to be considered one unit? If so, it might be better to write the second letter as lower case.
There are twelve different symbols. If each gets used once, the number of combinations (arrangements) is
12x11x10x9x8x7x6x5x4x3x2x1 = 12! =
479,001,600
If smaller groups of symbols can also be used, you get en even larger number of combinations
