Meanings

1. A radially symmetric Latin square.
   • Thus, Parker squares of different types may lie in the same isomorphism class and, a fortiori, in the same isotopism or main class of latin squares. 2015, A. Donald Keedwell, József Dénes, Latin Squares and their Applications, →ISBN, page 287:
   • The use of Parker squares in the construction of sets of mutually orthogonal Latin squares is then examined. 2004, Mathematical Reviews, page 8484:
   • A main class will contain a certain type of Parker square if and only if each square in the class is isotopic to a Parker square of that type. 2004, Ian M. Wanless, “Diagonally cyclic latin squares”, in European Journal of Combinatorics, volume 25, number 3:
