Doubly transitive groups and quandles
Leandro Vendramin (Universidad de Buenos Aires, Argentina)
Abstract: We prove that for n>2 there exists a quandle of cyclic type of size n
if and only if n is a power of a prime number. This establishes a
conjecture of S. Kamada, H. Tamaru and K. Wada. As a corollary, every
finite quandle of cyclic type is an Alexander quandle. We also prove
that finite doubly transitive quandles are of cyclic type. This
establishes a conjecture of H. Tamaru.
