We show that, for the O'Nan sporadic simple group, there is no Rwpri and (IP) 2 geometry of rank 6 with a maximal parabolic subgroup isomorphic to M 11 and that there is no Rwpri and (IP) 2 geometry of rank 5 with a maximal parabolic subgroup isomorphic to J 1 . This last result permits us to show t

β¦ Synopsis
This paper reports on a new and independent existence proof for the sporadic simple group Ly of Lyons, using only two permutations of degree 9 606 125, computed by Cooperman, Finkelstein, Tselman, and York. We will show that these two permutations generate a group G Ly, by first computing a base and strong generating set for G, and then checking the two hypotheses for Ly from Lyons' original paper. Moreover, this produces a new presentation for Ly.

## Abstract We consider the Hamiltonian system in IR^__N__^ given by where __V__ : IR^__N__^ rarr; IR is a smooth potential having a non degenerate local maximum at 0 and we assume that there is an open bounded neighborhood ft of 0 such that V(__x__) < __V__(0) for __x__ Ξ΄ Ξ© / {0}, __V(x)__ = __V
