The $q$-space is defined by the following equations over $(x,y,z)$:
$xy=qyx$
$yz=qzy$
$zx=qxz$
The transformations of the $q$-space are matrices $A$ such that $A$ and $A^t$ are automorphisms of the relations. We obtain so $36=2.18$ relations for the coefficients of $A$. Can we have a quantum group with this construction following the definition of the $q$-plane and $Sl_q(2)$?
