This conclusion is not universally accepted. Forsyth for example, argues that the writings of numerous Jesuit missionaries in Brazil in the sixteenth century makes a very strong case for cannibalism among the indigenous Tupi speaking Indians (Forsyth, 1983). Most anthropologists would agree, however

β¦ Synopsis
It is well known that a triplewhist tournament TWh(v) exists only if v β‘ 0 or 1 (mod 4) and v = 5, 9. In this article, we introduce a new concept TWh-frame and use it to show that the necessary condition for the existence of a TWh(v) is also sufficient with a handful possible exceptions of v β {12, 56}

Let Forb(G) denote the class of graphs with countable vertex sets which do not contain G as a subgraph. If G is finite, 2-connected, but not complete, then Forb(G) has no element which contains every other element of Forb(G) as a subgraph, i.e., this class contains no universal graph.
Let N = N (q) be the number of nonzero digits in the binary expansion of the odd integer q. A construction method is presented which produces, among other results, a block circulant complex Hadamard matrix of order 2 Ξ± q, where Ξ± β₯ 2N -1. This improves a recent result of Craigen regarding the asympt
