all the possible sequences for numbers 1,2,3,4,5,6,7,8,9,10 in groups of 5.

so I need to write a VB6 program that will generate all the possible sequences for numbers 1-10 in groups of 5.  
below is a starting sequence but not sure how to do it in a program.

1 2 3 4 5 61 2 3 4 5 10
1 2 3 4 6 7
1 2 3 4 5 7
1 2 3 4 5 8
1 2 3 4 5 9

1 2 3 4 6 8
1 2 3 4 6 9
1 2 3 4 6 10
1 2 3 4 7 8
1 2 3 4 7 9
1 2 3 4 7 10

etc
