Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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