Presentation

minimal degreeμ(G) = 45
transitive degreeμt(G) = 2432

A minimal faithful permutation representation — 5 generators on 45 points:

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