Perfect 1-factorisations of <i>K</i><sub style="">16</sub>

We report the results of a computer enumeration that found that there are 3155 perfect 1-factorisations (P1Fs) of the complete graph K16. Of these, 89 have a nontrivial automorphism group (correcting an earlier claim of 88 by Meszka and Rosa ['Perfect 1-factorisations of K16 with nontrivial automorphism group', J. Combin. Math. Combin. Comput. 47 (2003), 97-111]). We also (i) describe a new invariant which distinguishes between the P1Fs of K16, (ii) observe that the new P1Fs produce no atomic Latin squares of order 15 and (iii) record P1Fs for a number of large orders that exceed prime powers by one.
