Help with number generating

I need help on coding this or help with VB. I have VB 2010

First GS = Random number 1-60
second GS = Random number 1-60
third GS = Random number 1-60
fourth GS = Random number 1-60
fifth GS = Random number 1-60
SIXTH GS = Random number 1-50 ----- 50 NOT 60

The numbers need to be generated in sets of 6. so the above GS's need to be generated ALL TOGETHER. once, then twice, So on a so forth. So there should be 6 numbers generated at one time. Yet all seperate numbers. 6 numbers in a set.

I need to also know which SETS OF 6 come up the LEAST, and which come up the MOST out of this generator. I NEED THIS TO generate sets of 6 LIKE 175,223,510 TIMES.

for example --------> 5, 10, 19, 27, 32 and 49 ---------------This is 6 GS's in ONE SET--------------- This needs to happen a lot of times. 175,223,510 times.

Please help!
