n-ary associativity
From HandWiki
In algebra, n-ary associativity is a generalization of the associative law to n-ary operations. Ternary associativity is
- (abc)de = a(bcd)e = ab(cde),
i.e. the string abcde with any three adjacent elements bracketed. n-ary associativity is a string of length n + (n − 1) with any n adjacent elements bracketed.[1]
