| Research Abstract |
There are three results. 1) p-adic properties of the number of homomorphisms from a finite abelian p-group to symmetric groups were obtained. In particular, the exponent of p of the decomposition of such numbers into prime factors was made clear. There are 6 different types of the results. 2) The exponent of 2 in the decomposition of one plus the number of involutions in alternating groups or wreath products of a cyclic group of order 2 by alternating groups groups into prime factors could be described as 2-adic integers. 3)p-adic properties of the number of homomorphisms from the direct product of two cyclic p-groups to wreath product of a cyclic p-group by symmetric groups were obtained. The results are closely related to that for the number of homomorphisms to symmetric groups.
