Sharply 2-transitive groups of projectivities in generalized polygons
نویسنده
چکیده
The group of projectivities of (a line of) a projective plane is always 3-transitive. It is well known that the projective planes with a sharply 3-transitive group of projectivities are classi/ed: they are precisely the Pappian projective planes. It is also well known that the group of projectivities of a generalized polygon is 2-transitive. Here, we classify all generalized quadrangles, all /nite generalized hexagons, and the parameter sets of all /nite generalized octagons with a sharply 2-transitive group of projectivities. c © 2001 Elsevier Science B.V.

Sharply 2-transitive sets of permutations and groups of affine projectivities
Using new results on sharply transitive subsets, we determine the groups of projectivities of finite affine planes, apart from (unknown) planes of order 23 or 24. The group of all projectivities of a geometry G is a measure for the complexity of G: this group tends to be rather large if G is far from being a classical geometry. See [PS81] for more information on the role of projectivities in ge...
متن کاملSharply $(n-2)$-transitive Sets of Permutations
Let $S_n$ be the symmetric group on the set $[n]={1, 2, ldots, n}$. For $gin S_n$ let $fix(g)$ denote the number of fixed points of $g$. A subset $S$ of $S_n$ is called $t$-emph{transitive} if for any two $t$-tuples $(x_1,x_2,ldots,x_t)$ and $(y_1,y_2,ldots ,y_t)$ of distinct elements of $[n]$, there exists $gin S$ such that $x_{i}^g=y_{i}$ for any $1leq ileq t$ and additionally $S$ is called e...

متن کاملAn Essay on the Ree Octagons
We coordinatize the Moufang generalized octagons arising from the Ree groups of type 2 F4. In this way, we obtain a very concrete and explicit description of these octagons. We use this to prove some results on suboctagons, generalized homologies, Suzuki-Tits ovoids and groups of projectivities of the Ree octagons. All our results hold for arbitrary Ree octagons, finite or not.
متن کاملSharply 2-transitive Groups with Point Stabilizer of Exponent 3 or 6
Using the fact that all groups of exponent 3 are nilpotent, we show that every sharply 2-transitive permutation group whose point stabilizer has exponent 3 or 6 is finite.
