Presentation

minimal degreeμ(G) = 29
transitive degreeμt(G) = 320

A minimal faithful permutation representation — 3 generators on 29 points:

(1,2,3,4,5)(6,7)(8,10)(9,11)(12,13)(14,15,20,25)(16,26,17,28)(18,24,19,23)(21,29,22,27);(10,13)(14,16)(15,21)(17,20)(18,29)(19,27)(22,25)(23,28)(24,26);(6,8)(7,10)(9,12)(11,13)(14,17,20,16)(15,22,25,21)(18,29,19,27)(23,28,24,26)
