On a Class of Almost Contact Metric Manifolds of Maximal Mobility

A special class of almost contact metric manifolds $M^{2n+1}(\eta,\xi,\Phi,g)$ of maximal mobility is studied. In terms of a special coordinate system, we calculate the components of the structure objects of $M^{2n+1}$ and find basis vector fields of the Lie algebra of infinitesimal automorphisms of $M^{2n+1}$.
