Presentation

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

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

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