Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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