abelian square

hi folks,

i found 'abelian squares' in the context of patterns of n symbols of length 2n like 'abcd.cdba' where 'cdba' is a permutation of the first half 'abcd'.
however, in those texts it is not explained (maybe just not clear enough for me) what is 'abelian' and where is the 'square' ??

any hints ?

thanks
dvh
