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);(4,7)(8,10)(11,12)(13,15)(14,16)(17,18)(19,20,23,22)(21,25,26,24);(12,13)(16,17)(21,26)(24,25);(3,4)(5,8)(6,7)(9,10)(11,13,15,12)(14,16,18,17)(19,21)(20,24)(22,25)(23,26);(3,5,6,9)(4,8,7,10)(11,14,15,18)(12,16,13,17)(19,22,23,20)(21,25,26,24)
