Hello,

I have the following naive question.

The vertices of perles 8-dimensional irrational polytope are expressed in terms of the square root of 5, denoted r5.

For example one coordinate of one vertex is " -1/2 + 1/2r5".

I am not fully certain whether this expression is -1/2 + (1/2)r5 or -1/2 + 1/(2r5) , although I suspect the latter.

Thanks
