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