Abstract

In this paper the concept of outer product for R
4
is considered. By using this
outer product a new product on R
5
is introduced. R
5 with this product and usual addition
and scalar multiplication is an associative algebra. Via this algebra a new representation
for quaternions as a Lie group is presented. Moreover a representation for SU(2) is
deduced. 

Keywords
