Abstract: | We explicitly compute the outer automorphism group Out 1
M of the fundamental group of the Hantzsche — Wendt manifoldM. It is an extension 1(2)3Out1
MS
321, but not the semidirect product (2)3(S
32) as claimed in 3] (see also 4]). As a consequence, we get a quick algebraic computation of the symmetry groups of the Borromean rings and the figure-8-knot. |
