I do not succeed to handle free products of groups or vector spaces.

In the case of two vector spaces E and F the product (E,F) is the same thing that the free product E * F

I rad this article

https://en.wikipedia.org/wiki/Free_product

i would like to construct a free product in simple cases (say with groups of 2*2 matrices or somehthing

like that)

thanks
