Presentation

minimal degreeμ(G) = 45
transitive degreeμt(G) = 576

A minimal faithful permutation representation — 3 generators on 45 points:

(1,2,3,4,5,6,7,8,9)(14,15,17,21,18,22,27,33,19,23,28,34,29,35,39,43)(16,20,25,31,26,32,38,42,24,30,36,40,37,41,44,45);(10,11,12,13)(14,16)(15,20)(17,25)(18,26)(19,24)(21,31)(22,32)(23,30)(27,38)(28,36)(29,37)(33,42)(34,40)(35,41)(39,44)(43,45);(16,24)(20,30)(25,36)(26,37)(31,40)(32,41)(38,44)(42,45)
