ABC No Rio was created in 1980.

(eg. Aa Bb Cc)

First would be to find out all the different combinations of these traits

ABC ABc AbC Abc aBC aBc abC abc

Then would be to make a "cross" out of them

ABC ABc AbC Abc aBC aBc abC abc

ABC

ABc

AbC

Abc

aBC

aBc

abC

abc

Then would be to 'fill in' the cross by adding them up

ABC ABc AbC Abc aBC aBc abC abc

ABC AABBCC AABBCc AABbCC AABbCc AaBBCC AaBBCc AaBbCC....

ABc

AbC

Abc

aBC

aBc

abC

abc

Hope the rest you can figure out,

Sincerely,

*diag*

yes abc=abc

Because a,b, and c are the first three letters of the alphabet
