Define the numbers of what are these numbers INC-C2, – C3. Example combinations take Table. 2. C2 – 1,2,3,10,30 We see that the combination consists of three numbers, the first group of numbers from 1 to 9, a number of the second group of numbers from 10 to 19 rooms and one of the fourth group of numbers from 30 to 36 rooms. (Similarly see: Richard Linklater). C3-1,2,3,20,30 This combination is different from previous order that she, instead of one number from 10 to 19 the number of rooms there is the third group of numbers from 20 to 29 rooms.

In the condition, the task was a sequence of numbers from 36 1nomera numbers, then numbers of the second group of numbers from 10 to 19 number, in combination, repeated before the third group of numbers from 20 to 29 numbers that follow sequentially numbered from 10 to 19 rooms. The conclusion is that, in combination 639 part numbers INC – C2. 3. Define the 5 numbers from 36 numbers for version number 639. Total numbers of participating in 639 combinations will be: 639h5 = 3195 define the number of times all the numbers from 1 to 9 numbers are repeated. Knowing that the average value of the number of repetitions is -4 it is: 3195: 4 = 798.75 = 88.7 798,75:9 To determine the three numbers of a group of numbers from 1 to 9 numbers for the version number should be 639 to calculate the whole number of repetitions to a combination of number 639 and after it.
