HELP: Find repeating combos ?

I have this table in Excel:

Column1	Column2	Column3	Column4	Column5	Column6
50	24	8	4	3	1
50	18	8	7	1	1
49	8	7	5	3	1
49	15	4	3	1	1
48	15	10	8	4	3
44	20	5	3	1	1
43	4	3	3	3	1
42	16	5	5	1	1
41	14	10	6	3	3
41	13	11	8	6	5
40	9	5	3	2	1
39	9	7	4	4	3
39	8	7	6	4	1
39	9	6	4	3	3
38	8	7	5	3	2
38	14	8	4	4	3
38	17	15	10	8	8
37	10	10	6	2	2
37	19	8	4	3	1
37	23	23	3	2	2

MANY NUMBERS (AT LEAST 1000 ROWS IN THIS TABLE)

The numbers may repeat in one or more columns.
It may be something like:
1 1 1 1 1 1
OR any combo:
e.g.:
23 5 3 1 1 1

As you maybe note already, numbers are sorted from higher to lower.
number in Column1 >= number in Column2 >= number in Column3 >= number in Column4 >= number in Column5 >= number in Column6.

I want a way to find out how many times each combo of six numbers are repeating in this table.
e.g.
23 5 3 1 1 1 appears 17 times
1 1 1 1 1 1 appears 38 times and so on.

Any help with this, please ?

Thank you so much !
