Thetranslation planes of order 81 admitting 
Abstract
Johnson and Prince have classified all translation planes of order 81 that admit
, where the 3-elements are elations. In this article, it is shown that whenever
acts as a collineation group on a translation plane of order 81, the problem can always be reduced to the elation case. Hence, there is a complete classification of all translation planes of order 81 admitting
; there are exactly 14 translation planes of order 81 admitting
.
