Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 64

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

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