It is the same as trebles. Start with how many selections there are and then times by the next number in the sequence and times that by the next number. Then divide that number by 1x2x3. For example 5 selections 5x4x3 =120 / 1x2x3 =6 = 20 trebles in 5 selections. But because it is a reverse forcadt you need to then times that by 2
120. The numbers are factorials: 1, 1x2, 1x2x3, etc.
1 2 and 3. 1+2+3=6 1x2x3=6
Factorial. n! = 1x2x3x4x.....x(n-2)x(n-1)xn. Examples: 3! = 1x2x3 = 6 7! = 1x2x3x4x5x6x7=5040
3x2 2x3 1x2x3 2x1x3 3x1x2 1x2x3

1+2+3 6; 1X2X3 6

Number is 6 1X2X3= 6 1+2+3= 6
1,2 and 3 1+2+3 = 6 and 1x2x3= 6
1+2+3=6 1x2x3=6 123
6 = (1+2+3) 6 = (1x2x3)
1 2 and 3. 1+2+3=6 1x2x3=6
1, 2 and 3 fit the bilkl nicely for this, 1+2+3 is 6. 1x2x3 is 6
