Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 6 generators on 28 points:

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