Well I've looked at your example and I think I know whats happening from cell G3 to BM 13 , you signify where a number appears in each result. What I do not understand is what any of this has to do with Column J ? Column J is the fifth number in each result (Ball 5) so what did you mean by:-
determine repetition numbers pair >=2 (column J) ?
If you enter the formula =IF(COUNTIF($B3:$F3,G$2),G$2,"") in cell G3 and copy this formula along to column BM and also copy the formulas down to row 13 so as to fill in the are G3:BM13 with copies of the formula, I think that does what you illustrated.
Also if you enter =IF(COUNTIF(H3:H13,">1")>1,H2,"") in cell H16 and copy that along the row to cell BM16, then that flags up the identity of a repeated number over the 11 draws you show, which is what your example appeared to be doing ( a few differences here and there).
Just what you are doing with the dates, I'm not quite sure since there seems to be no consistent pattern in your illustration.
For example:- in column H the number 2 appears three times , two of them on 19/3/2014 and once on 15/03/2014. you have entered both these dates under date repetition.
In column O the number 9 appears twice, once on each date but you only enter 19/03/2014.
In column BE number 51 appears twice, once on each date, but you only enter 19/03/2014.
So what is your criterion for entering a repetition date ?
