Hi "zz".
It is possible to generate overlaped combinations in an easy way. Chose menu "Package" -> Generate. In the "Generator" dialog window check "Generate tickets with random numbers", enter count in field "tickets to generate" and chose range of numbers. In order to fulfil your request you must allow the "maximum match" in "x" numbers. Click "OK" and wait. It is possible (when the number "tickets to generate" is too high and range of numbers is relatively small and if you allow match in "x" numbers small enough) that computer will generate the essential part (99,99%) of resulting set quickly and then it will continue with search for remaining part. In such case you can close the process clicking "Cancel" in dialog. Tickets generated so far are writen in the package. Each ticket in package will then match any other ticket maximally in the allowed count of numbers.
