A note on the Figueroa planes
\textit{R. Figueroa} [Math. Z. 181, 471-479 (1982; Zbl 0477.51009)] and \textit{C. Hering} and \textit{H.-J. Schaeffer} [Lecture Notes Math. 969, 187-190 (1982; Zbl 0498.51009)] constructed nondesarguesian projective planes of order \(q^ 3\) which contain a subplane of order \(q\) such that the full automorphism group induces \(P\Gamma L(3,q)\) on the subplane. It is pointed out that this construction also works for infinite planes.
