Nonabelian Sets with Distinct k -sums A.M. Odlyzko, AT&T Bell Laboratories;W.D. Smith, NECII 02/10/93 ABSTRACT: A modified Bose-Chowla construction of sets with distinct sums of $k$-element subsets is presented. In infinitely many cases it yields sets with a certain multiplicative symmetry. These sets are then used to construct large sets $S$ in certain nonabelian groups with the property that all $k$-letter words with letters from $S$ are distinct. KEYWORDS: $S_K$-SETS, SETS WITH DISTINCT SUMS, ADDITIVE BASIS, GROUPS, COMBINATORICS
