Presentation

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

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

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