Richard,

Excellent entry. Couple observations.

1. Does not meet criteria for SetOption('NoVarsInStrings','On')

2. On small range 1,10 duplicates are found seeming repeatably (granted it is possible that on such a small range this is as random as KiX may be able to get to)

Examples of return data when range is set to 1,10

Aside from that, very nice entry in the challenge. Thank you for taking the time to enter.
