Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 5 generators on 28 points:

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