Cycles in graphs, .VK and N∩VK=φ..If g Is k-connected, then it is an old result of Dirac that G ε C(k, 0). It is easy to produce k-connected graphs which are not C(k+1, 0). Hence the best we can hope of an arbitrary k-connected graph is that it is C(k, 0). However if we restrict our attention to k-connected regular

Sequenceable groups, generalized complete mappings, neofields and block designs,to light. Also, some progress has been made in determining classes of groups which are sequenceable or R-sequenceable. We survey these results, point out their inter-connections and indicate some unsolved problems.

Generalised hadamard matrices whose rows and columns form a group,matrices of type p. for C.×...×C. exist. We also show that the matrices for C. of each possible order are unique up to equivalence..We indicate a connection between strongly independent sets and row group Hadamard matrices..We show that the irreducible factors of a group Hadamard matrix under tensor

Two new sequences of ovals in finite desarguesian planes of even order, three of which are collinear. One of the most influential theorems of finite geometry has been Segre‘s 1954 result that every oval of a finite Desarguesian plane of odd order is an irreducible conic. In 1957 and 1962 he showed that the even order case is more complicated by constructing two infinit
