Hi mayeven;

I am sorry but I am not following what you are trying to do. Can you be a little clearer?

The author please? There are like 14000 titles like that one. Please provide me with chapter and problem number.

I hope you are not talking about the blog?!

Perhaps if you did not wait for the last minute you would not be rushing now...

I also do not agree it is hard. So far you have not made it clear enough for me to understand.

follow e.g one

(a1,a2) vs (b1,b2 )

a1,a2

a1,b1

a1,b2

a2,b1

a2,b2

b1,b2.

n add c1,c2

like abcd in full combination it

ABC BAC CAB DAB

ACB BCA CBA DBA

ABD BAD CAD DAC

ADB BDA CDA DCA

ACD BCD CBD DBC

ADC BDC CDB DCB

solves for

a) a1,a2 vs b1,b2 vs c1,c2

b) a1,a2 vs b1,b2 vs c1,c2 vs d1,d2

c) a1,a2 vs b1,b2 vs c1,c2 vs d1,d2, e1,e2 ....

replaces abc with a1 a2 b1 b2 c1 c2 d1 d2 e1 e2 that simple ....
