Okay, put this formula in D1:

=INDIRECT("A"&MOD(INT((ROW(A1)-1)/(COUNTA(B:B)*COUNTA(C:C))),COUNTA
(A:A))+1)+INDIRECT("B"&MOD(INT((ROW(A1)-1)/COUNTA(C:C)),COUNTA(B:B))
+1)+INDIRECT("C"&MOD(ROW(A1)-1,COUNTA(C:C))+1)

and copy it down.

This assumes that you have no headers, so that your data begins in row
1.

Hope this helps.

you want a list 50,000 items?

If so, give me some details of how your data is laid out. I did
something similar last week for a poster, and if your data is
something like this:

* A_B * * *B_C * * * C_D
* time * * *time * * * time
* time * * *time * * * time
(to 40) * *(to 50) * *(to 25)

then I can adapt it for you to go into column D - one formula copied
down.

Hope this helps.

I have 40 observed travel times for A to B, 50 for B to C and 25 for C to D. *
Is there a way in Excel to calculate a list of all the possible total travel
