Hmm... funny information.
I think it's more interesting to know the probability of *some* hit for
a given set of three random numbers.
The kind of "average" given above seems quite meaningless to me,
since sequences are multiply counted obviously. What sense will it make
to count all the sequences starting 0, 1, 2 ... ? Here *one* random
sample with numbers 0,1,2 will get an overwhelming number of hits,
which drives the average up without real meaning.
With friendly regards
