Abstract
In this note, it is shown that the maximum number of pairwise touching translates of an n simplex is at least n+3 for n=7 , and for all n?5 such that n?1mod4 . The current best known lower bound for general n is n+2 . For n=2 k ?1 and k?2 , we will also present an alternative construction to give n+2 touching simplices using Hadamard matrices.
